The Interplay among Localization Spin-Orbit Coupling and Ferromagnetism in the Diluted Magnetic Semiconductor (Ga,Mn)As

ORAL

Abstract

We combine the typical medium analysis and dynamical mean field approximation to study the electronic and magnetic properties of the diluted magnetic semiconductor Ga1-xMnxAs. We use the k.p model to describe the electronic structure of GaAs with spin-orbit coupling. By using the typical medium analysis, localization due to disorder induced by the Mn doping is appropriately captured, which allows us to study the interplay among the localization, spin-orbit coupling and ferromagnetism. This study can serve as a guidance to the more realistic first-principles calculation of Ga1-xMnxAs.
