摘要：

The magneto-optical (MO) Kerr effect in the manganese-platinum compounds MnPt3 and PtMnSb is studied from first principles, using density-functional bandstructure theory. The calculated Kerr spectra give a good description of the huge Kerr rotations found experimentally in these compounds. The origin of the Kerr rotation is discussed in relationship to the band structure and the spin-orbit (SO) interaction strength of Pt.
