Abstract

We extend the Blonder–Tinkham–Klapwijk approach to studying the effects of barrier strength and spin polarization on coherent spin‐polarized transport in ferromagnet (FM)/iron‐pnictide‐superconductor (SC)/FM structures with s~±~‐paring for the SC. It is demonstrated that the effects of barrier strength and spin polarization on the particular features of oscillations of all the reflection and transmission probabilities, and differential conductances with energy in ferromagnetic and antiferromagnetic alignments of the magnetizations of the two FMs are different, which are also different from those for the s~++~ model.

Within a scattering framework, a theoretical study is presented for the spin-polarized quasiparticle transport in ferromagnet/d-wave superconductor junctions. We find that the subgap conductance behavior is qualitatively different from a nonmagnetic junction, and can also be significantly different
