N2 - Magneto-optical spectra in FePt(x Å)/Pt(50 Å) multilayers prepared by the ion-beam sputtering technique were measured between 1 and 6 eV. Simulation by the virtual optical constant method, assuming the existence of a magnetic Pt layer at the interface, provided a fairly good explanation of the x-dependence of the magneto-optical spectra. The magnetic coupling between FePt and Pt was found to be antiparallel for x ≥ 50 and parallel for x < 50.
