Multiple- to single-gap superconductivity crossover in Nb${}_5$Ir${}_{3-x}$Pt${}_x$O alloys

Y. Xu, S. Jöhr, L. Das +5

By using mostly the muon-spin rotation/relaxation ($\mu$SR) technique, we investigate the superconductivity (SC) of Nb${}_5$Ir${}_{3-x}$Pt${}_x$O ($x=0$ and 1.6) alloys, with $T_c = 10.5…
