%X Superconducting (SC) in equal
molar NbTaTiZr-based high-entropy alloys (HEAs) that were added with Fe, Ge,
Hf, Si, and/or V was observed. According to investigation on crystal structure,
composition, and the relationship between critical temperature and e/a ratio,
as indicated in Matthias¡¯ empirical rule, the main superconducting phase was
that enriched with Nb and Ta. The coherence length (¦Î) that was calculated from the carrier density reveals
that ¦Îvalue has the same order of magnitude of several hundreds of
Angstroms as those binary Nb-Ti and Nb-Zr alloys showed.
