The vortex dynamics in a low-temperature superconductor deposited on top of a rectangular array of micrometer size permalloy triangles is investigated experimentally. The rectangular unit cell is such that neighboring triangles physically touch each other along one direction. This design stabilizes remanent states which differ from the magnetic vortex state typical of individual noninteracting triangles. Magnetic force microscopy images have revealed that the magnetic landscape of the template can be switched to an ordered configuration after magnetizing the sample with an in-plane field. The ordered phase exhibits a broad flux-flow regime with relatively low critical current and a highly anisotropic response. This behavior is caused by the spontaneous formation of two separated rows of vortices and antivortices along each line of connected triangles. The existence of a clear flux-flow regime at zero external field supports this interpretation. The density of induced vortex-antivortex pairs is directly obtained using a high-frequency measurement technique which allows us to resolve the discrete motion of vortices. Strikingly, the presence of vortex-antivortex rows gives rise to a self-organized synchronized motion of vortices which manifests itself as field independent Shapiro steps in the current-voltage characteristics.

Magneto transport characterization of the Sn-doped TbMnO3 manganites

in Journal of Alloys & Compounds (2009), 467(1-2), 35-40

The structural, magnetic and electrical transport properties of the Sn-doped TbMnO3 manganites are studied by X-ray diffraction, ac susceptibility, dc magnetization and electrical resistivity measurements. The Sn doping into the Tb and Mn sites of TbMnO3 compresses the unit cell and changes parameters of the antiferromagnetic phase whereas the magnetic moment of Mn are only weakly affected. The electrical resistivity of doped manganites is reduced and the activation energy EA is determined for the thermally activated conduction. [less ▲]

Le travail au féminin

Le travail féminin a bien entendu ses particularités. Mais nos sociétés sont-elles attentives à leurs implications ? Et les pratiques d’aujourd’hui témoignent-elles de changements significatifs sur le plan d’un « plus » d’égalité entre femmes et hommes ? Que révèlent les situations, les évolutions et les tendances actuelles ? Ces questions sont rencontrées par Annie Cornet. Il se trouve que l’approche attentive au « genre » - the gender - est déterminante pour donner à voir et à comprendre les évolutions en cours. Le « genre » et les stéréotypes culturels, de type sexiste, interviennent dans une multiplicité de domaines qui influencent l’emploi au féminin. [less ▲]

Case reports are the most accessible publications to the medical student or the practitioner. The appropriate selection of the clinical case that deserves publication is an important first step in the process. Afterwards, the report of the case requests much attention, as far as both content and presentation are concerned. The key-message emerging from the clinical case should be emphasized and supported by a clear-cut argumentation. Such an exercise, which might appear difficult at first glance, represents a valuable training for further more complex scientific publications. Here we give some practical advices to help the student or the practitioner who would like to present or publish a case report. [less ▲]

Use of cannabinoid CB1 receptor antagonists for the treatment of metabolic disorders.

Abdominal obesity is associated with numerous metabolic abnormalities, including insulin resistance, impaired glucose tolerance/type-2 diabetes, and atherogenic dyslipidaemia with low high-density lipoprotein (HDL) cholesterol, high triglycerides, and increased small dense low-density lipoprotein (LDL) cholesterol. A proportion of these metabolic disorders may be attributed to increased endocannabinoid activity. The selective cannabinoid 1 (CB1) receptor antagonist rimonabant has been shown to reduce body weight, waist circumference, insulin resistance, triglycerides, dense LDL, C-reactive protein (CRP), and blood pressure, and to increase HDL and adiponectin concentrations in both non-diabetic and diabetic overweight/obese patients. Besides an improvement in glucose tolerance in non-diabetic subjects, a reduction of 0.5-0.7% in haemoglobin A1C (HbA(1c)) levels was consistently observed in various groups of patients with type-2 diabetes. Almost half the metabolic changes could not be explained by weight loss, supporting direct peripheral effects of rimonabant. Ongoing studies should demonstrate whether improved metabolic disorders with CB1 receptor antagonists (rimonabant, taranabant, etc.) would translate into fewer cardiovascular complications among high-risk individuals.
