The magneto-optic response of Pt/Co superlattices is simulated to gain insight into the recent experimental findings of favorable information-storage characteristics. Major trends are reproduced qualitatively, and the calculations indicate that the Pt contributes significantly to the short-wavelength polar Kerr signal (at 4 eV). The influences of the wavelength, angle of incidence, component thicknesses, overcoat, and substrate on the rotation, ellipticity, and reflectivity are evaluated.
