µSR investigation of a 3d dominated lightweight high entropy alloy superconductor with high critical field and current density for technological applications
Abstract: High-entropy alloys (HEAs) challenge traditional alloy design by combining multiple principal elements in near-equiatomic ratios, resulting in high configurational entropy and atomic-scale disorder while maintaining simple crystalline structures. Initially celebrated for their exceptional mechanical properties, HEAs are now gaining attention for exhibiting superconductivity despite strong disorder?a phenomenon that defies conventional BCS theory. This proposal focuses on the lightweight HEA superconductor Sc0.2Ti0.2V0.2Nb0.2Cu0.2, notable for its low density and high critical field. Such properties make it a promising candidate for weight-sensitive applications in aerospace, cryogenics, and quantum technologies. Despite its disorder, this material demonstrates fully gapped s-wave superconductivity with preserved time-reversal symmetry and strong electron-electron correlations. We propose muon spin relaxation and rotation (µSR) experiments to probe its gap symmetry, penetration depth, and potential symmetry breaking. These investigations aim to unravel the role of disorder in superconductivity, offering insights into the pairing mechanism and guiding the design of next-generation lightweight superconductors for advanced technological applications.
