We are studied the electronic and magnetic properties of the A-site ordered perovskite CaCo3V4O12 within the density-functional theory using the generalized gradient approximation (GGA) with the consideration of strong Coulomb correlations (GGA + U) in the framework of the fully relativistic spin-polarized Dirac linear muffin-tin orbital method of band-structure calculation. The x-ray absorption spectra and x-ray magnetic circular dichroism at the Ca, Co, and V K-edges are investigated theoretically. The effect of the electric quadrupole E2 transitions and magnetic dipole M1 transitions are analysed. The calculated results are in good agreement with experimental data.
Key words: electronic band structure, magnetic moment, GGA, x-ray absorption spectra, x-ray magnetic circular dichroism, double perovskites.
