Theory And Experiment

The magnetic specific heat, magnetization and low-field magnetic susceptibility of Co-based diluted magnetic semiconductors Zn 1−x Co x Se and Zn 1−x Co x S have been calculated by using a Hamiltonian which takes into account both the Heisenberg-type nearest-neighbor exchange interactions and spin-orbit interactions. A fair agreement between theory and experiment is obtained. No magnetization steps are predicted in the ranges of temperature and magnetic field considered here.

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 Ga 1-x Mn x As is considered and compared with experimental data.
