Title: Superconductivity in ternary rare earth palladium Heusler compounds

Technical Report ·
OSTI ID:6755472

A study of the ternary rare earth palladium Heusler compounds of composition RPd/sub 2/X, where R=Sc, Y, Er, Tm, Yb, or Lu, and X=Sn or Pb, was undertaken to investigate the behavior of their superconducting transition temperature under pressure. The transition temperature was linearly depressed to 20 kbar, with dT/sub c//dP typically of the order of 10/sup -5/ K/bar, which can be explained by a stiffening of the simple cubic palladium sublattice with increasing pressure. The lattice parameter and transition temperature are very disorder-dependent, increasing to maximum values after annealing for two days; resistivity measurements indicate that no phase transitions occur below room temperature.
