Investigating time-reversal and pairing symmetry in topological superconductor NbxBi2Se3

Abstract: NbxBi2Se3 is a potential topological superconductor candidate as it preserve Dirac surface dispersion and also superconducting at the same time. It belongs to the Eu representation of the D3d point group which allows the appearance of the chiral topological phase and breaks time-reversal symmetry (TRS) spontaneously. Indeed, Y. Qiu et al. has recently reported finite magnetization at zero field below the superconducting transition temperature (Tc) which can be attributed to TRS breaking fields. muSR technique is one of the most sensitive probe to detect such broken TRS unambiguously. Here we propose to study the magnetic and superconducting properties of NbxBi2Se3 by a combination of zero-field (ZF) and transverse-field (TF)-muSR measurements at the MUSR spectrometer. We ask for 4 days of MUSR beamtime to complete this proposed study.
