Infuence of correlation effects on the of magneto-optical properties of half-metallic ferromagnet NiMnSb
arXiv:cond-mat/0609375 · doi:10.1103/PhysRevB.74.140411
Abstract
The magneto-optical spectra of NiMnSb were calculated in the framework of the Local Spin Density Approximation (LSDA) combined with Dynamical Mean-Field Theory (DMFT). Comparing with results based on plain LSDA, an additional account of many-body correlations via DMFT results in a noticably improved agreement of the theoretical Kerr-rotation and ellipticity spectra with corresponding experimental data.
