摘要：
We have prepared CoxNi1-x/Pt multilayers by evaporation under ultrahigh vacuum conditions and studied their magnetic and magneto-optical properties. Addition of Co to Ni increases the surface anisotropy and T(C). For instance, in Co0.3Ni0.7/Pt for t(Co, Ni) = 4.5 angstrom, one observes a perpendicular rectangular M-H loop with a coercivity of 800 Oe and T(C) of 180-degrees-C. The polar Kerr rotation of this sample shows a peak value of 0.3-degrees at the photon energy of 4 eV. These characteristics are very interesting for realising magneto-optic storage media capable of working in blue light.
