Superconducting properties and<i>μ</i>SR study of the noncentrosymmetric superconductor Nb<sub>0.5</sub>Os<sub>0.5</sub>
The properties of the noncentrosymmetric superconductor ($\alpha$-$\textit{Mn}$ structure) Nb$_{0.5}$Os$_{0.5}$ is investigated using resistivity, magnetization, specific heat, and muon spin relaxation and rotation ($\mu$SR) measurements. These measurements suggest that Nb$_{0.5}$Os$_{0.5}$ is a weakly coupled ($\lambda_{e-ph}$ $\sim$ 0.53) type-II superconductor ($\kappa_{GL}$ $\approx$ 61) having a bulk superconducting transition temperature $T_c$ = 3.07 …
