Essay

The energy band and magnetic structures as well as x-ray spectra for the (Zn, T)O diluted magnetic semiconductors and A-site ordered double perovskites CaMnTi2O6 and CaCo3V4O12 are obtained theoretically from first principles using the spin-polarized fully relativistic Dirac linear muffin-tin orbital band structure method. The (Zn, T)O are studied for T = V, Mn, Fe, and Co. X-ray absorption and magnetic circular dichroism spectra at V-, Mn-, Fe- (L2,3-edges only), Co-, Zn- K- and L2,3-edges as well as а O-K-edge for (Zn, T)O; for CaMnTi2O6 at Mn-, Ti-L2,3-edges and O-K-edge; for CaCo3V4O12 at Ca-, Co- and V-K-edges are calculated, analyzed and compared with the experimental data.
