Abstract
In this work, we establish the bulk superconductivity of a high-quality single crystal of monoclinic BiPd (α-BiPd, space group P21) below 3.8 K by studying its electrical resistivity, magnetic susceptibility, and heat capacity. We establish that it is a clean type-II superconductor with moderate electron-phonon coupling and determine its superconducting and normal state parameters. Although α-BiPd is a noncentrosymmetric superconductor with an appreciable electronic heat capacity (γ = 4 mJ/mol K2), the effect of spin-orbit splitting of the electronic bands at the Fermi level seems to be small as reflected by the absence of large anisotropy of the bulk normal and superconducting properties of α-BiPd.
