| Abstract: | The coherent potential approximation (CPA) is used on a minimal model of diluted magnetic semiconductors (DMS), where the carrier feels a nonmagnetic potential at a magnetic impurity site, and its spin interacts with the localized spins of the magnetic impurities through exchange interactions. The CPA equations for one particle Green function are derived and the optical conductivity dependence on the system parameters and temperature is investigated. For illustration, the case of Ga1-xMnxAs is considered and compared with experimental data. © World Scientific Publishing Company. |
