Superconducting proximity effect in a diffusive ferromagnet with spin-active interfaces
Superconducting proximity effect in a diffusive ferromagnet with spin-active interfaces
We reconsider the problem of the superconducting proximity effect in a diffusive ferromagnet bounded by tunneling interfaces, using spin-dependent boundary conditions. This introduces for each interface a phase-shifting conductance Gphi which results from the spin dependence of the phase shifts acquired by the electrons upon scattering on the interface. We …
