The properties of the noncentrosymmetric superconductor (α-[Formula: see text] structure) NbOs have been investigated using resistivity, magnetization, specific heat, and muon spin relaxation and rotation (μSR) measurements. These measurements suggest that NbOs is a weakly coupled ([Formula: see text]) type-II superconductor ([Formula: see text]), having a bulk superconducting transition temperature T = 3.07 K. The specific heat data fits well with the single-gap BCS model indicating nodeless s-wave superconductivity in NbOs. The μSR measurements also confirm [Formula: see text]-wave superconductivity with the preserved time-reversal symmetry.
利用电阻率、磁化强度、比热以及μ子自旋弛豫和旋转（μSR）测量，对非中心对称超导体（α-[化学式：见原文]结构）NbOs的性质进行了研究。这些测量表明，NbOs是一种弱耦合（[化学式：见原文]）的II型超导体（[化学式：见原文]），其体超导转变温度(T_c) = 3.07 K。比热数据与单能隙BCS模型拟合良好，表明NbOs中存在无节点的s波超导性。μSR测量也证实了具有时间反演对称性的[化学式：见原文]波超导性。
