Probing superconducting gap structure and time reversal symmetry state of LaRh2Ga2 through ?SR measurements

Abstract: Motivated by our recent muon spin relaxation and rotation ( SR) studies which revealed time reversal symmetry breaking in s-wave isotropic-gap BCS superconductors CaPd2Ge2, CaPd2As2, and SrPd2As2, we propose to carry out SR measurements to probe superconductivity in 122-type compound LaRh2Ga2. LaRh2Ga2 forms in CaBe2Ge2-type primitive tetragonal structure which lacks a mirror symmetry along c-axis (local inversion symmetry breaking). Our magnetic susceptibility, electrical resistivity and heat capacity all reveal occurrence of superconductivity in LaRh2Ga2 with a Tc of 3.45 K. Further investigations using SR measurements are highly required to probe the superconducting gap structure, pairing symmetry and time reversal symmetry state of LaRh2Ga2. We therefore propose to carry out SR measurements on LaRh2Ga2 using the MUSR spectrometer.
