We prepared Co/Pd1-xAux multilayers on glass substrates by RF magnetron sputtering at room temperature. Co/Pd1_xAux multilayers exhibit a magnetic easy axis perpendicular to the film plane up to a larger magnetic layer thickness than do Co/Pd multilayers. In particular, Co/Pdo.7oAuo.3o multilayers became perpendicular at 33 Å. The magnetic anisotropy can be explained by the strain effect. The role of the magnetoelastic energy due to the in-plane strain in the system is pointed out and discussed. We also investigated the magnetooptical polar Kerr effect of these multilayers. The polar Kerr rotation angle θk increases when the Au concentration is 4.5 at.% compared to Co/Pd multilayers but decreases with increasing Au content.
