Various temperature-responsive N-isopropylacrylamide-based functional copolymers were prepared and used for the stabilization of iron oxide nanoparticles. The copolymers investigated are poly(acrylic acid)-b-poly(N-isopropylacrylamide) (PAA-PNIPAM) and poly(acrylic acid)-b-poly(N-isopropylacrylamide)-b-poly(acrylate methoxy poly(ethylene oxide)) (PAA-PNIPAM-PAMPEO), with different molecular weights. The coated nanoparticles were characterized in terms of size by a combination of dynamic light scattering (DLS) and transmission electron microscopy (TEM). A sharp temperature transition was confirmed by particle size measurements vs. temperature. In addition, the stealthiness of the coated nanoparticles has been assessed in vitro by the haemolytic CH50 test. These measurements evidenced the crucial role of the PEO segments on the stealthiness of the nanoparticles and thus that such copolymers are particularly suitable for biomedical applications. Preliminary experiments of alternating magnetic field induced heating were performed and specific absorption rates of the various samples were recorded. [less ▲]

Compositions in the series Ni2-xCoxGeMo3N (0 ex e2),Co2Ge1-xGaxMo3N (0<x e0.7),Co2-xFexGeMo3N (0 e x e 2), and Co2-xFexGe0.5Ga0.5Mo3N (0 e x e 0.8) have been synthesized by the reductive nitridation of binary oxides and studied by appropriate combinations of magnetometry, transport measurements, neutron diffraction, and M€ossbauer spectroscopy. All of these compositions adopt the cubic η-carbide structure (a ∼ 11.11 A ̊ ) and show a resistivity of ∼10 -3 Ω cm. No long-range magnetic order was observed in Ni 2-xCoxGeMo3N, although evidence of spin freezing was observed in Co2GeMo3N. The introduction of gallium into this composition leads to the onset of antiferromagnetic ordering at 90 K in Co2Ge0.3Ga0.7Mo3N. The magnetic structure consists of an antiferromagnetic arrangement of ferromagnetic Co4 groups, with an ordered magnetic moment of 0.48(9) μB per cobalt atom. The same magnetic structure is found in Co0.5Fe1.5GeMo3N and Co1.2Fe0.8Ge0.5Ga0.5Mo3N. The former orders above room temperature with an average moment of 1.08(3) μB per transition-metal site, and the latter at 228 K with an average moment of 1.17(4) μB per site. The magnetic behavior of these compounds is discussed in terms of the electron count within each series. [less ▲]

The tetragonal intermetallic compounds U2Pd2In and U2Pd2Sn have been studied by means of magnetic susceptibility, magnetization, specific heat, electrical resistivity, and x-ray- and neutron-diffraction techniques. The compounds order antiferromagnetically at 36 and 41 K, respectively, and have enhanced electronic specific-heat coefficients γ of 393 and 203 mJ/mol f.u. K**2, respectively. At low temperature, the nearest-neighbor U-U spacing is along the c axis in both compounds, though in U2Pd2Sn the in-plane U-U distance is shorter at room temperature. This crossover is due to motion of the U atoms within the cell rather than anisotropy of the thermal contraction. It is now well established in several classes of (1:1:1) uranium ternary intermetallic compounds that the strong magnetic anisotropy is correlated with the direction of nearest-neighbor U-U links; the moments are almost invariably oriented perpendicular to such links. This is also the case for U2Pd2In and U2Pd2Sn, where the moments lie in the tetragonal basal plane in a canted arrangement along [110] and [1¯10] directions. Of four such Shubnikov subgroups of P4/mbm, one is clearly preferred by the data. At 10 K, the magnetic moments extracted are (1.6±0.2) Bohr magneton and (2.0±0.1) Bohr magneton per U atom in U2Pd2In and U2Pd2Sn, respectively. [less ▲]

An orthorhombic DyMnO3 single crystal has been studied in magnetic fields up to 14 T and between 3 K and room temperature. The field dependent ordering temperature of Dy moments is deduced. The paramagnetic Curie Weiss behavior is related mainly to the Dy3+sublattice whereas the Mn sublattice contribution plays a secondary role. DC magnetization measurements show marked anisotropic features, related to the anisotropic structure of a cubic system stretched along a body diagonal, with a magnetic easy axis parallel to the crystallographic b axis. A temperature and field dependent spin flop transition is observed below 9 K, when relatively weak magnetocrystalline anisotropy is overcome by magnetic fields up to 1.6 T. [less ▲]

It is shown that filling the holes of a drilled bulk high-temperature superconductor (HTS) with a soft ferromagnetic powder enhances its trapping properties. The magnetic properties of the trapped field magnet are characterized by Hall probe mapping and magnetization measurements. This analysis is completed by a numerical model based on a 3D finite-element method where the conductivity of the superconducting material is described by a power law while the permeability of the ferromagnetic material is fixed to a given value and is considered uniform. Numerical results support the experimental observations. In particular, they confirm the increase of trapped flux that is observed with Hall probe mapping after impregnation. [less ▲]

A polycrystalline sample of Fe2GeMo3N has been synthesized by the reductive nitridation of a mixture of binary oxides in a flow of 10% dihydrogen in dinitrogen. The reaction product has been studied by magnetometry, neutron diffraction and M€ossbauer spectroscopy over the temperature range 1.8 # T/K # 700. The electronic properties have been modelled by DFT and Monte Carlo methods. Fe2GeMo3N adopts the cubic h-carbide structure with a ¼ 11.1630(1) at 300 K. The electrical conductivity was found to be 0.9 mU cm over the temperature range 80 # T/K # 300. On cooling below 455 K the compound undergoes a transition to an antiferromagnetic state. The magnetic unit cell contains an antiferromagnetic arrangement of eight ferromagnetic Fe4 tetrahedra; the ordered atomic magnetic moments, 1.90(4) mB per Fe atom at 1.8 K, align along a <111> direction. DFT predicts an ordered moment of 1.831 mB per Fe, albeit with a N eel temperature of >549 K. Monte Carlo calculations confirm that the experimentally determined magnetic structure is the lowest-energy antiferromagnetic structure. These results emphasise the potential of these computational methods in the search for new magnetic materials. [less ▲]

Stoichiometric LaMnO3 is an insulator whose A-type antiferromagnetic structure at low temperature is mainly connected to the Jahn-Teller distortion of the MnO6 octahedra. The substitution of non magnetic d(10) Ga3+ ions on the manganese site disrupts the orbital and spin orderings of the manganese ions and has a strong influence on the physical properties. The antiferromagnetic order is progressively destroyed while the ferromagnetic component increases. At the same time, the distortion of the orthorhombic cell decreases and the high temperature structural Jahn-Teller transition disappears. Such studies on manganese site substitutions give insight into the physics of the Mn-O three-dimensional network, which is supposed to be the key feature in the CMR manganites.

The structural and magnetic properties of the granular iron nitride-alumina composite materials: (FexN)(0.2)(Al2O3)(0.8) and (FexN)(0.6)(Al2O3)(0.4), fabricated using high-energy ball milling have been determined by using X-ray diffraction, Mossbauer spectroscopy, and magnetization measurements. The Mossbauer spectra, fit with a distribution of hyperfine fields between zero and 40 T. indicate that the weighted average field decreases with increasing milling time. The isomer shift increases with milling time because of a reduced iron 4s-electron density at the grain boundaries. Coercive fields as high as 325 and 110 Oe are obtained for (FexN)(0.2)(Al2O3)(0.8) at 5 and 300 K, respectively; the increase in the coercive field upon cooling indicates the presence of superparamagnetic particles. The coercive field increases with milling time because of the reduced particle size. The decrease in the magnetization results from the increase in both the superparamagnetic fraction and the concentration of surface defects with increased milling time. [less ▲]

This paper aims at reporting magnetic properties of bulk polycrystalline Bi2Sr2Ca0.8Dy0.2Cu2O8-y samples textured under a magnetic field. The microstructure of these materials is highly anisotropic and exhibits particular features needed to be taken into account in order to interpret their magnetic and electrical properties. First the AC magnetic susceptibility has been measured for several magnetic fields (H parallel to ab and H parallel to c) and compared to the electrical resistivity data. The structure of the chi'' peak is shown to be related to the chemical content distribution of the superconducting grains. Next, the magnetic flux profiles have been extracted from the magnetic measurements using the Campbell-Rollins procedure. The anisotropy of the flux profiles and their peculiar curvature behaviour for H parallel toc point out the role of both grain platelet structure and the presence of secondary phases. From these results, we conclude that the magnetic properties of such magnetically textured materials do not allow for a reliable extraction of the critical current density J(c) but essentially probe geometric effects. Such effects have to be taken into account for improving the manufacture of attractive high-T-c materials. (C) 2001 Elsevier Science B.V. All rights reserved. [less ▲]

This communication aims at reporting the superconducting properties of several bulk melt-processed DyBa2Cu3O7-x samples determined by using various measuring techniques. The original single domain material was first cut into 9 similar cubic samples which have been characterized by AC susceptibility, flux profiles and DC magnetization. The results indicate good quality melt-processed (RE)BCO materials with Tc = 89 K. Next, the effect of post oxygen annealing treatments on these samples was studied. The influence of the non-uniformity of the oxygen content on the magnetic property anisotropy is discussed. Finally, additional magnetic measurements were carried out by using a couple of parallel pick-up coils wound on the same sample. From the results we conclude that geometric effects have to be taken into account in order to extract the critical current density from the magnetic properties. [less ▲]

The purpose of the present work is to determine experimentally and numerically how the magnetic flux density both inside and outside a large grain, bulk high temperature superconductor is modified when placed in the vicinity of axisymmetric ferromagnetic components. The investigated superconductors are bulk (RE)Ba2Cu3O7 cylinders of a few cm³. The ferromagnets are of various sizes and shapes, machined out of well characterized, soft magnetic alloys of high permeability. Both superconductor and ferromagnet have the same diameter and are cooled at the liquid nitrogen temperature (T = 77 K). The properties of the superconductor / ferromagnet (SC/FM) hybrid structures are investigated through surface (Hall probe) and volume measurements carried out in the fully magnetized remanent state and under complete cycles of field applied either parallel or perpendicular to the sample c axis. The design of a suitable volume characterization method for large samples and its validation through comparison with other measurements is part of the present work. Numerical models based on the Brandt and finite element methods are compared with the measurements and used to investigate configurations and physical quantities that are not accessible experimentally. We show that the ferromagnet acts as a magnetic short-circuit and creates a low reluctance path that drives the flux lines directly towards the edges of the superconducting magnet. The zone above the ferromagnet is shielded from the flux trapped inside the superconductor. Conversely, the flux density can often be enhanced on the face opposite to the ferromagnet (superconductor side); it is suggested that the flux density increase due to the ferromagnet is more significant when combined to a rather thin superconducting pellet. In all the studied cases, the presence of the ferromagnet was found to increase both the average trapped flux inside the superconductor and the magnetic moment of the whole SC/FM structure (including the ferromagnet). The ferromagnet ability to divert magnetic flux lines depends on whether it is partially or fully saturated. This saturation is found to be governed in the remanent state by the ferromagnet thickness d, its saturation magnetization M_sat and the flux produced by the superconductor (proportional to its critical current density J_c). The amount of diverted / shielded flux does not change once the ferromagnet is fully saturated and the effect of the ferromagnet becomes relatively less important as the generated flux increases. Hybrid structures are therefore relevant even when the trapped flux density exceeds the typical saturation magnetization of ferromagnetic materials (≈ 2 T). For a given critical current the higher the saturation magnetization and/or the thicker the ferromagnetic material, the larger the shielding effects on the ferromagnet side and the higher the trapped field on the superconductor face for the investigated sample. For a ferromagnetic disc with the same diameter a as the superconductor, the most suitable ferromagnet thickness d^* can be roughly estimated by a simplified analytical expression d^*≈(J_c0 a^2 )⁄( 6M_sat ), below which nearly full saturation of the FM occurs and above which weak thickness dependence is observed. The magnitude of the supercurrent is an important parameter but its particular J_c (B) dependence is found not to be a crucial parameter affecting the remanent state properties of the modelled hybrid configurations. In addition, the time relaxation of the trapped magnetization was found not to be influenced by the presence of the ferromagnet, within measurement uncertainties. The ferromagnet also influences the magnetic flux density when the assembly is subjected to an external magnetic field. The penetration of the magnetic flux inside the superconductor is delayed in the vicinity of the ferromagnet. The hysteresis loops of the flux density averaged on the superconductor volume show a combination of diamagnetic and ferromagnetic behaviour for SC/FM structures. It appears to be the simple superimposition of the hysteresis cycles of the superconductor and the ferromagnet at high applied field (i.e. exceeding the apparent saturation of the ferromagnet). This simple “addition” rule can be used to effectively predict the magnetic behaviour of larger or more complex hybrid structures and to modulate the magnetic flux density. As in the remanent sate, a thicker ferromagnet has a more significant effect on the whole hysteresis loop of the superconductor, but this effect varies less than proportionally to the increase in the ferromagnet volume. For a given volume of ferromagnetic material, the shape of an unsaturated ferromagnet is not of prime importance provided that the ferromagnet covers the entire surface of the superconductor. A succession of holes and ferromagnetic sections could be used to modulate the flux density. A similar volume of ferromagnetic material was shown to have more influence on the average remanent volume flux density if it is split on both faces of the superconductor to form a FM/SC/FM structure instead of a SC/FM structure. Two additional advantages of ferromagnets were identified in this work. First, the ferromagnet was shown to be beneficial in improving the field gradient – and therefore the magnetic levitation force – outside the superconductor. Second, the addition of the ferromagnetic disc on one side of the superconductor reduces the collapse of the trapped flux density when subjected to several cycles of magnetic field applied perpendicularly to its remanent magnetization (parallel to the c-axis), i.e. in the so-called “crossed-field configuration”.

We combine imaging of the proton aurora from the SI12-IMAGE instrument with ionospheric convection measurement from the SuperDARN radar network to analyze the cycle of magnetic flux opening and closure of the Earth magnetosphere. Interaction between the solar wind and the Earth geomagnetic environment causes a reconfiguration of the magnetic field that connects the interplanetary magnetic field (IMF) to the geomagnetic field. This reconnection process produces open magnetic field lines (i.e. field lines of the magnetosphere that close through the interplanetary medium) that are dragged to the magnetotail by the solar wind flow, where they eventually reconnect again, back to a closed topology. The SI12 imaging of the Doppler-shifted Lyman-α emission of the proton aurora is used to estimate the location of the boundary separating open and closed field lines at ionospheric altitude. We then estimate the open magnetic flux of the Earth magnetosphere, encircled by this boundary. The rate of reconnection causing a variation of the open magnetic flux can be expressed as a voltage in application of Faraday’s law. This voltage is measured along the open/closed field line boundary determined from the imaging data. The electric field associated with the voltage has two origins: motion of the boundary and the ionospheric field. We use the ionospheric electric field deduced from ionospheric convection measurement from the SuperDARN to estimate the reconnection voltage at the magnetopause (flux opening) and in the magnetotail (flux closure) accounting for the motion of the open/closed field line boundary determined from the SI12 images. The method is applied during several (strong) geomagnetic storms. These intervals are characterized by large values of open flux and reconnection rates, as a result of coupling between the solar wind and the geomagnetic environment. We present these results in terms of a magnetospheric mode that develops under strong coupling with the solar wind, a condition known to be prone to the development of sawtooth events, characterized by overloading of the magnetosphere with open magnetic flux.

Objective-To evaluate efficacy of intra-articular injection of gadolinium tetra- azacyclododecane tetraacetic acid (gadolinium-DOTA) for delineating fragmented medial coronoid processes (FMCP) and lesions on the medial aspect of the humeral condyle (MAHC). Sample Population-14 cubital joints in 9 dogs. Procedure-Magnetic resonance imaging (MRI) was performed with and without intra-articular injection of a solution of 2 mmol of gadolinium-DOTA/L. Arthrographic images obtained after injection of contrast medium were compared with those obtained without contrast medium. Evidence of contrast medium around or in the medial coronoid process and infiltration of contrast medium in subchondral bone lesions was recorded, Twenty-four hours after imaging, arthroscopy was performed, and lesions detected were correlated with results of MRI. Results-An abnormal coronoid process was diagnosed in 13 of 14 joints. A fragmented process (free) was seen in 7 of 14 joints; nondisplaced mineralized medial tin situ) coronoid processes were evident in 4 joints; and nondisplaced unmineralized medial coronoid processes were evident in 2 joints. Lesions on the MAHC were diagnosed in 4 of 12 joints. In 5 joints, a hyperintense signal resulted from contrast medium that infiltrated between the fragmented process and ulna. In 2 joints, contrast medium did not infiltrate completely around the process and was stopped by an isointense structure tie, abnormal cartilage). Subchondral bone lesions were enhanced by use of contrast medium. Conclusion and Clinical Relevance-Use of arthrography enabled us to identify FMCP easily, but did not provide important additional information about changes on the medial coronoid process, compared with MRI performed without contrast medium.

SETTING: Infertility and IVF Unit, in an university medical center. PATIENT: A 31-year-old healthy patient with a 3-year history of primary male infertility. INTERVENTION: Standard IVF-ET treatment cycle, using a GnRH-agonist (long protocol) and hMG for ovarian stimulation. RESULTS: A cornual triplet pregnancy is described with the approach for the diagnosis. Magnetic resonance imaging was complementary to endovaginal sonography for early diagnosis and permitted a timed conservative management. CONCLUSIONS: When transvaginal ultrasound findings did not provide an accurate location of the pregnancy, MRI was indicated to confirm the diagnosis. [less ▲]
