Band structure model of magnetic coupling in semiconductors

Materials Science 2009-11-11 v1

Abstract

We present a unified band structure model to explain magnetic ordering in Mn-doped semiconductors. This model is based on the pp-dd and dd-dd level repulsions between the Mn ions and host elements and can successfully explain magnetic ordering observed in all Mn doped II-VI and III-V semiconductors such as CdTe, GaAs, ZnO, and GaN. This model, therefore, provides a simple guideline for future band structure engineering of magnetic semiconductors.
