Abstract
The Kerr rotation of the Co-O films which is a newly developed perpendicular magnetic films was investigated. Saturation magnetization decreases as the oxygen content of the film increases, however the Kerr rotation angle does not decrease and the same value of 15 min to 25 min as the pure cobalt film was obtained. This can be accounted for by the high transmittance of the Co-O films. Co-O film on the cobalt film significantly increased Kerr rotation by the new enhancement effect.
