Inelastic Scattering in Point Contacts Between a Normal Ferromagnetic Half-Metal and a Superconductor

A model for conductance in N/S point contacts, including spin polarization\footnote{G.J. Strijkers, Y. Li, F.Y. Yang, C.L. Chien and J.M. Byers, Phys. Rev. B 63, 104510 (2001).} is modified to incorporate inelastic scattering, i.e., quasiparticle finite-lifetime effects. For the half-metal limit of this model, we present calculations of zero bias conductance as a function of temperature and normalized conductance as a function of voltage, for the entire parameter space of the model.
