Electronic and Transport Properties of Liquid Quenched Amorphous (Mo_(1-xx)Ru_x)₈₀P₂₀ Superconductors

Abstract

Results of superconductive properties and magnetic susceptibilities of amorphous molybdenum based alloys obtained by liquid quenching are presented and discussed. These alloys have superconducting transition temperatures ranging from 3 K to 9 K. Correlation between T_c and magnetic susceptibility is observed. However, the predicted variation of density of states at the Fermi level with electron valence fails to explain the observed variation in the upper critical field within the framework of "dirty alloy" theories.
