Electronic transport through ferromagnetic and superconducting junctions with spin-filter tunneling barriers

F. S. Bergeret, A. Verso, A. F. Volkov

We present a theoretical study of the quasiparticle and subgap conductance of generic $X/I_{sf}/S_M$ junction with a spin-filter barrier $I_{sf}$, where $X$ is either a normal $N…
