摘要

The complex magneto-optical Kerr rotation spectra of Fe/Cu and FeCo/Cu bilayers and compositionally modulated films (CMF) were studied experimentally and theoretically. In the bilayers, an enhancement of Kerr ellipticity ε_k by a factor of 5 was observed at long wavelength side, while the Kerr rotation θ_k can only be enhanced by a factor of 2 around the plasma edge of Cu. In the CMFs, ε_k was enhanced by 60% but no θ_k enhancement was observed. Theoretical analyses showed that both the magnitude of effective ε̃_xye and the magnitude and signs of effective A_e and B_e are important for magneto-optical enhancement.
