Muon spin rotation/relaxation study of newly discovered novel layered superconductor NaSn2As2

Abstract: The low dimensionality affects the electronic structure of materials, which could realize a high transition temperature or unconventional pairing mechanisms. Recently Mizuguchi et al. discovered the superconductivity in a layered tin arsenide NaSn2As2. Measurements of electrical resistivity and specific heat confirm the bulk nature of superconductivity of NaSn2As2 with Tc=1.3 K. In this compound the SnAs layers will be a basic structure providing another universality class of a layered superconducting family, and it provides a new platform for the physics and chemistry of low-dimensional superconductors with lone pair electrons. We propose to use zero-field, transverse field and longitudinal field muSR to investigate the microscopic superconducting properties, such as symmetry of electron pairing, carrier effective mass and time-reversal symmetry of NaSn2As2.
