Temperature Dependence of the Lower Critical Field of the Noncentrosymmetric Superconductor α ‐BiPd

Résumé

Temperature variation of the lower critical H c1 field in the noncentrosymmetric superconductor α-BiPd is probed by local magnetization measurements using Hall micromagnetometry, performed down to 0.3 K in a magnetic field applied along the crystallographic b axis. Below a critical temperature T c ≃ 3.8 K, a conventional H c1 ðTÞ dependence is found, typical for a single-band s-wave superconductor. The obtained data imply an absence of spin-triplet component in the superconducting wavefunction and marginal multiband effects in this material, which contradicts some literature reports.
