Spin-orbit fields in ferromagnetic metal/semiconductor junctions

TL;DR

This paper discusses the inaccuracies in previous methods for determining spin-orbit couplings in ferromagnetic metal/semiconductor junctions, highlighting the need for corrected approaches.

Contribution

It identifies errors in the perturbation theory methodology used to extract spin-orbit coupling values, correcting previous results.

Findings

Previous figures (2 and 3) are incorrect due to methodological errors.

Corrected methodology provides accurate spin-orbit coupling values.

Highlights importance of proper theoretical approaches in spintronics research.

Abstract

The methodology used to obtain the values of the spin-orbit couplings from the spin expectation values from perturbation theory was incorrect. As a result Figs. 2 and 3 are incorrect.
