Spin-flip scattering and nonideal interfaces in dirty ferromagnet/superconductor junctions
Spin-flip scattering and nonideal interfaces in dirty ferromagnet/superconductor junctions
We study the proximity-induced superconducting correlations as well as the local density of states of a ferromagnet, in a ferromagnet/$s$-wave superconductor heterostructure. We include the effects of spin-flip scattering, nonideal interfaces, and the presence of impurities in the sample. We employ the quasiclassical theory of superconductivity, solving the Usadel equation …
