Scattering theory of interface resistance in magnetic multilayers

Abstract

The scattering theory of transport has to be applied with care in a diffuse\nenvironment. Here we discuss how the scattering matrices of heterointerfaces\ncan be used to compute interface resistances of dirty magnetic multilayers.\nFirst principles calculations of these interface resistances agree well with\nexperiments in the CPP (current perpendicular to the interface plane)\nconfiguration.\n
