Abstract
CuCr2Se4 is one of the few compounds that exhibits a magneto-optical (MO) K err angle of greater than one degree at room temperature. To better underst and the origin of this effect, the MO properties of ferromagnetic CuCr2X4 ( X=S, Se, Te) spinel chalcogenides are evaluated using fully relativistic lo cal-density electronic structure calculations. Treating the 3d electronic s tates within the standard hand description, excellent agreement with the me asured MO spectra is obtained. The calculations are analyzed to further elu cidate aspects of the Ken rotation.
