Boron based new high entropy alloy superconductor Mo0.11W0.11V0.11Re0.34B0.33

Abstract

Superconducting high entropy alloys (HEAs) are new members of disordered superconductors. We report the synthesis and investigation of a new superconducting high entropy alloy Mo${}_{0.11}$W${}_{0.11}$V${}_{0.11}$Re${}_{0.34}$B${}_{0.33}$ (MWVRB). It crystallized in the tetragonal CuAl${}_2$ crystal structure with space group (I4/$mcm$). Comprehensive transport, magnetization and heat capacity measurements confirmed bulk type-II superconductivity having transition temperature T${}_C$ = 4.0 K. The low temperature electronic specific heat suggests a fully gapped superconducting state in weak coupling limit.
