Electrical transport and magnetic properties of superconducting Mo[sub 52]Re[sub 48] alloy

We report the study of temperature and magnetic field dependence of magnetization and resistivity of Mo52Re48 alloy superconductor. The transition temperature (TC) and zero temperature limit upper critical field (HC2(0)) are estimated to be about 13.4 K and 8.5 T which are higher than those for any Mo-Re alloys reported in literature. The critical current density is estimated to be about 6.2 × 108 A/m2 at 2 K which is nearly comparable to most of the commercial superconductors. These properties indicate that if tuned properly Mo-Re system may be useful for the high field application.
