Spin resolved Andreev reflection in ferromagnet-superconductor junctions with Zeeman splitting
arXiv:cond-mat/9908465 · doi:10.1209/epl/i2000-00532-1
Abstract
Andreev reflection in ferromagnet-superconductor junctions is derived in a regime in which Zeeman splitting dominates the response of the superconductor to an applied magnetic field. Spin-up and spin-down Andreev reflections are shown to be resolved as voltage is increased. In the metallic limit, the transition from Andreev to tunnel conductivity in the spin-up channels has a non trivial behavior when spin polarization is increased. The conductance is asymmetric in a voltage reversal.
