Magnetic pair breaking and local lattice distortion in Cr-containing high-entropy alloy superconductors
Abstract
High-entropy alloy superconductors provide a unique platform to explore the interplay between disorder, lattice distortion, and superconductivity. Here, the author investigate the effect of incorporating the magnetic element Cr in a high entropy alloy superconductor (TiVTa)${}_{0.6}$Nb${}_{0.4\ensuremath{-}x}$Cr${}_{x}$, revealing a systematic suppression of superconductivity despite nearly constant valence electron count. We show that magnetic impurity scattering drives pair breaking consistent with Abrikosov--Gor'kov theory in this highly disordered system, while strong local lattice distortion coexists with long-range crystalline order.
