Abstract :
[en] Synthesis and preliminary studies on U1−xNpxPd2Al3 and U1−xNpxRu2Si2 are presented. In all Np compounds measured here, no superconducting transition was found down to 1.4 K. In U1−xNpxPd2Al3 a small amount (0.01 less-than-or-equals, slant x less-than-or-equals, slant 0.05) of Np induces an anomaly in the lattice parameters and presents in resistivity measurements a sharp minimum at low temperature.
