Quasi-classical approach to perpendicular transport through metallic magnetic superlattices

Abstract

We present an extended quasi-classical theory of the perpendicular transport of electrons through magnetic multilayers. The two-point conductivity and the perpendicular resistivity are analytically studied by treating the spin-dependent scattering at interfaces as bulk asymmetric scattering within mixed interlayers. The results obtained are shown to be equivalent to those derived from the quantum method, indicating that there is a direct connection between the Boltzmann and the Kubo approaches.
