Abstract

Band structure, density of states, total energy and magnetic moment are calculated for ideal and defective supercell CdTe and CdMnTe by ab initio method. The optimization of crystal structure and atom relaxation has been carried out. The band gap, local levels in the band gap and magnetic moments are defined for various defective supercell CdTe and CdMnTe in ferromagnetic and antiferromagnetic states. It has been defined that as Mn atoms, the vacancy, interstitial atom and Frenkel pair in the crystal structure form magnetic moment.
