Abstract

- In order to understand and manipulate the properties of diluted magnetic semiconductors, a precise knowledge of interactions in these systems should be available. In this chapter, we review ab initio studies on DMS, in particular, calculations of ordering temperatures by Monte Carlo simulations. We argue why we do not expect large values of ordering temperatures from the point of view of dilute spin system, short ranged magnetic exchange interactions and magnetic percolation. Also, we show results of atomistic spin dynamics using Landau–Lifshitz–Gilbert equations for Mn-doped GaAs. The effects of strong electron correlation on the electronic and magnetic structure are demonstrated by dynamical mean field theory.
