TL;DR
This paper develops a scattering theory approach to calculate interface resistance in dirty magnetic multilayers, demonstrating good agreement with experimental data in the CPP configuration.
Contribution
It introduces a method to compute interface resistances using scattering matrices, specifically addressing diffuse environments in magnetic multilayers.
Findings
First principles calculations match experimental interface resistance measurements.
The scattering theory effectively models transport in diffuse magnetic multilayers.
The approach is validated in the current perpendicular to the interface plane configuration.
Abstract
The scattering theory of transport has to be applied with care in a diffuse environment. Here we discuss how the scattering matrices of heterointerfaces can be used to compute interface resistances of dirty magnetic multilayers. First principles calculations of these interface resistances agree well with experiments in the CPP (current perpendicular to the interface plane) configuration.
