Type-I superconductivity in single-crystal Pb2Pd

We have investigated the superconducting properties in a single crystal of superconductor ${\mathrm{Pb}}_{2}\mathrm{Pd}$ via various techniques including, magnetization, AC transport, transverse field muon spin rotation and relaxation, heat capacity. All measurements confirm transition temperature ${T}_{C}=3.0\ifmmode\pm\else\textpm\fi{}0.1\phantom{\rule{0.28em}{0ex}}\mathrm{K}$. Electronic specific-heat data are well described by BCS expression, suggesting that opens an isotropic gap on entering state. Specific-heat jump ${\ensuremath{\lambda}}_{e\text{\ensuremath{-}}ph}$ value categorize as moderately coupled superconductor. Magnetization along with Ginzburg-Landau parameter, $\ensuremath{\kappa}$ $1/\sqrt{2}$ demonstrates is type-I
