$\mu$SR and magnetometry study of superconducting 5% Pt doped IrTe${}_2$

Abstract

We present magnetometry and muon spin rotation ($\mu$SR) measurements of the superconducting dichalcogenide Ir${}_{0.95}$Pt${}_{0.05}$Te${}_2$. From both sets of measurements we calculate the penetration depth and thence superfluid density as a function of temperature. The temperature dependence of the superfluid densities from both sets of data indicate fully gapped superconductivity that can be fit to a conventional s-wave model and yiel fitting parameters consistent with a BCS weak coupling superconductor. We therefore see no evidence for exotic superconductivity in Ir${}_{0.95}$Pt${}_{0.05}$Te${}_2$.
