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 the plain LSDA, the additional account of many-body correlations via DMFT results in a noticeably improved agreement of the theoretical Kerr rotation and ellipticity spectra with corresponding experimental data.
