| Abstract Scope |
High entropy alloys (HEAs), composed of multiple elements that are all present in major proportion, with the simple structures observed attributed to the high configurational entropy of the random mixing of the elements on their lattice sites [1]. The first superconducting HEA, Ta0.34Nb0.33Hf0.08Zr0.14Ti0.11, was discovered in 2014 [2], highlighting the potential of HEA in practical applications. HEAs exhibiting bulk superconductivity, excellent specific strength, high-temperature mechanical stability and cryogenic fracture resistance are promising materials for superconducting magnets. In the present study, three HEAs - (NbHf)0.75(ZrTi)0.25, (NbZr)0.75(HfTi)0.25 and (NbTi)0.75(ZrHf)0.25 - were investigated, all with a valence electron concentration of 4.375 and a simple body-centered cubic structure. Their superconducting properties, assessed by magnetization and specific heat measurements, were compared with data from other superconductors.
