Abstract
Highly precise electronic and magnetic property calculations on MnxGe1-x as a function of the location of Mn sites in a large supercell were used to investigate the nature and origin of ferromagnetism in magnetic semiconductors. For large Mn-Mn distances the coupling was not necessarily ferromagnetic. The exchange interaction between Mn ions obeyed the Ruderman-Kittel-Kasuya-Yosida analytic formula and oscillated as a function of the distance between them. The results explained the experimental effective magnetic moments and the observed large range of Curie temperature in MnxGe1-x.
