论文摘要
超导高熵合金（HEAS）是无序超导体的新成员。我们报告了新的超导高熵合金MO $ $ _ {0.11} $ W $ _ {0.11} $ v $ _ {0.11} $ re $ re $ $ _ {0.34} $ b $ _ {0.33} $（mwvrb）的合成和调查。它在带有空间群体（I4/$ MCM $）的四方Cual $ _2 $晶体结构中结晶。全面的运输，磁化和热容量测量确认了具有过渡温度t $ _ {C} $ = 4.0 K的体积II型超导率。低温电子特异性热量表明，在弱耦合极限的情况下，具有完全张开的超导状态。
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.
