ABSTRACT:
A magneto-optical memory element includes a glass substrate and an amorphous Nd-Gd-Fe ternary alloy magnetic recording thin-film having an axis of easy magnetization perpendicular to its surface. The magneto-optical memory element shows a preferable coercive force, a high Kerr rotation angle in the reproduced laser beam, and the Curie temperature suited for a stable operation.
