Abstract
Co-Pt alloy films with perpendicular magnetic anisotropy, 100% remanen ce, large coercivity and Kerr rotation were prepared by sputtering a c omposite target without any buffer layer. Effects of sputtering pressu re, substrate temperature, film thickness and Co content on the magnet ic and magneto-optical properties of the films are studied. X-ray diff raction analysis shows that the perpendicular magnetic anisotropy in C o-Pt alloy films is not directly related to the ordered CoPt3Li2 phase . (C) 1997 Elsevier Science B.V.
