Magneto-optic and transverse transport properties of non-collinear antiferromagnets

Abstract

Previous studies on the anomalous Hall effect in coplanar non-collinear antiferromagnets are revisited and extended to magneto-optic properties, namely magneto-optic Kerr effect (MOKE) and X-ray magnetic dichroism (XMCD). Starting from group-theoretical considerations the shape of the frequency-dependent conductivity tensor for various actual and hypothetical spin configurations in cubic and hexagonal Mn${}_{3}X$ compounds is determined. Calculated MOKE and X-ray dichroism spectra are used to confirm these findings and to give estimates of the size of the effects. For Mn${}_3$IrPt and Mn${}_3$PtRh alloys the concentration dependence of the anomalous and spin Hall conductivity is studied in addition.
