AbstractThe structural and magnetic properties of sputtered Ag/Co, Pd/Co, and AgPd/Co multilayered films were investigated. When substrate temperature during deposition (Ts) was set at room temperature, the easy magnetization axis of the Pd/Co films with Co thickness less than 7Å was normal to the film plane and that of the Ag/Co films was parallel. AgPd/Co multilayered films showed a transition of the preferred direction of magnetic moment from lying in the film plane towards lying along the film normal when increasing the Pd concentration above 81 at%. Moreover, an anomalous reduction of the saturation magnetization was found. The perpendicular magnetic anisotropy of Pd/Co films with low Ts increased with decreasing the thickness of Co layer. However, the Pd/Co films with high Ts showed opposite tendency.

AbstractThe very large perpendicular magnetic anisotropy of the order of 2 x 107 erg/cm3 at room temperature was found in CoJ-x Ptx(0<x<0.5) alloy thin films made by e-beam evaporation. The large magnetic anisotropy is likely related to the anisotropic Co-Co bonding distribution, which is similar to the cases of Co/Pt multilayers and FePt alloy thin films. The activation energy estimated for the ordering is approximately 0.3 eV, which is preferably compared to 0.2 eV for FePt. A model is proposed, for which both a short range and long range ordering are present, depending on substrate deposition temperature.
