Investigation of superconducting gap structure in NbPtSi using muon spin relaxation and rotation

Abstract: Superconductivity (SC) and spin-orbit (SO) interaction have been two separate emerging fields until very recently the correlation between them has been observed. The ternary equiatomic compounds exhibits SC at relatively high TC. We have reported muSR studies on ZrIrSi and HfIrSi. Recently, H. Suzuki and N. Kase et al. have reported SC in NbPtSi with TC = 1.24 K. Considering the high atomic number for Pt, one would expect the presence of strong SOC in NdPtSi. The temperature dependence of Hc2 (T) cannot be explained using a standard WHH theory, suggesting strong electron-phonon coupling and anisotropic gap are contributed to the enhancement of upper critical field. To study the role of SOC on the superconductivity of NbPtSi, we propose to investigate microscopic superconducting properties of NbPtSi using transverse field (TF) and zero field (ZF) musr on the MuSR spectrometer.
