Abstract: We have prepared COxNi1-x /Pt multilayers by evaporation under UHV conditions and studied their magnetic and magneto-optical properties. By adjusting the Co content it is possible to tailor the Curie temperature (TC) for magneto-optical storage application without trading off the other useful characteristics. For instance for x=0.3, for magnetic layers of the order of 5 Å one has a rectangular M-H loop with coercivity as high as 1.4 kOe with a polar Kerr rotation peak of 0.3 deg at the photon energy of 4 eV and a TC = 180°C. For x=0.5, one has similar properties but with a TC of 200°C. These materials hold very good promise for high density magneto-optical recording in the blue light.
