Abstract

Consecutive measurements of the magnetization curves and resistive transitions in magnetic fields have been made on PdH xT (x=H/Pd=0.9801−0.9957) foils between 2 and 10.4 K. The interpretation of the results is complicated by the fact that the magnetization curves are extremely irreversible and the hydrogen is distributed inhomogeneously in the samples. However, an analysis of the results shows PdH to probably be a type I superconductor with aT c of between 10.2 and 10.4 K, an HC(0) somewhat less than 900 G, and a κ of around 0.6 at absolute zero. Forx below about 0.995, PdH x becomes a type II superconductor due to the increasing resistivity of the material.
