【 摘 要 】

Superconducting high entropy alloys (HEAs) are emerging as an exotic class of superconducting materials, providing a unique opportunity to understand the complex interplay of disorder and superconductivity. We report the synthesis and detail bulk and microscopic characterization of a Nb60Re10Zr10Hf10Ti10 HEA alloy using transport, magnetization, specific heat, and muon spin rotation/relaxation (mu SR) measurements. Bulk superconductivity with transition temperature T-C = 5.7 K is confirmed by magnetization, resistivity, and heat capacity measurements. Zero-field mu SR measurements confirm that the superconducting state preserves time-reversal symmetry, and transverse-field measurements show that the superfluid density is well described by an isotropic s-wave model.
