Superconducting properties of the noncentrosymmetric superconductor LaPtGe

Abstract

We report superconducting properties of noncentrosymmetric superconductor LaPtGe which crystallizes in noncentrosymmetric $\alpha$-ThSi${}_2$ structure. The magnetization, resistivity and specific heat measurements confirm that LaPtGe is a type-II bulk superconductor with a transition temperature T${}_c$ = 3.05 $\pm$ 0.05 K. Muon-spin relaxation/rotation measurements confirms that time reversal preserved in the superconducting ground state.
