Role of interface transparency and spin-dependent scattering in diffusive ferromagnet/superconductor heterostructures
Role of interface transparency and spin-dependent scattering in diffusive ferromagnet/superconductor heterostructures
We present a numerical study of the density of states in a ferromagnet/superconductor junction and the Josephson current in a superconductor/ferromagnet/superconductor junction in the diffusive limit by solving the Usadel equation with Nazarov's boundary conditions. Our calculations are valid for an arbitrary interface transparency and an arbitrary spin-dependent scattering rate, …
