Noncentrosymmetric superconductors with $\ensuremath{\alpha}$-manganese structure has attracted much attention recently, after the discovery of time-reversal symmetry breaking in all the members of the ${\mathrm{Re}}_{6}X$ ($X=\text{Ti}$, Hf, Zr) family. Similar to ${\mathrm{Re}}_{6}X$, ${\mathrm{NbOs}}_{2}$ also adopts $\ensuremath{\alpha}\text{\ensuremath{-}}\text{Mn}$ structure and is found to be superconducting with critical temperature ${T}_{c}\ensuremath{\simeq}2.7$ K. The results of …
