In this paper, we present magnetometry and muon spin rotation ( SR) measurements of the superconducting dichalcogenide Ir_0.95Pt_0.05Te₂. 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 yield fitting parameters consistent with a BCS weak coupling superconductor. Finally, we therefore see no evidence for exotic superconductivity in Ir_0.95Pt_0.05Te₂.
