Abstract.
The effect of the Ni addition on the structure and magneto-optical (MO) properties is investigated with (CoPt3)1−xNix alloy films. The result shows that, lower Tc and higher Hc could be simultaneously obtained in the Ni range of 0.43–0.7. <111>> texture is not the only reason for perpendicular magnetic anisotropy in the present system. Although Ni addition reduces the Kerr rotation angle value in the blue-wave range, it slightly enhances the value in the red-wave range. The films investigated can be considered as suitable for perpendicular magnetic recording applications if the proper Ni addition range (0.43–0.5) is selected.
