Abstract
We investigate the superconducting gap structure of the intermetallic superconductor Mo3Sb7 single crystal by low-temperature thermal conductivity measurements. In zero field, the absence of a residual linear term κ 0 / T in the T → 0 limit provides strong evidence for nodeless superconducting gap. The field dependence of κ 0 / T is very similar to that of InBi, a typical s-wave superconductor in the dirty limit. These results demonstrate that Mo3Sb7 has nodeless s-wave superconducting gap, despite the opening of a spin gap at 53 K and the possible interplay between superconductivity and magnetism.
