Abstract
We have investigated the superconducting properties in a single crystal of the superconductor Pb2Pd via various techniques including, magnetization, AC transport, transverse field muon spin rotation and relaxation, and heat capacity. All measurements confirm the superconducting transition temperature TC=3.0±0.1K. Electronic specific-heat data are well described by the BCS expression, suggesting that Pb2Pd opens an isotropic gap on entering the superconducting state. Specific-heat jump and the λe−ph value categorize Pb2Pd as a moderately coupled superconductor. Magnetization and transverse field muon spin rotation measurements along with the Ginzburg-Landau parameter, κ < 1/2 demonstrates that Pb2Pd is a type-I superconductor.
