First-principles based semi-classical model for transport in magnetic layered structures

Abstract

We present a first principles based semiclassical model for transport in an inhomogeneous magnetic layered structure. The approach solves the Boltzmann transport equation using the band structure, Bloch wave velocities and scattering matrices, describing the reflection and transmission of Bloch waves from interfaces, derived from ab-initio local spin density electronic structure calculations. The model has been tested for thick Co and Cu films as well as for a set of Co/Cu/Co spin valves.
