MAGNETOOPTISCHES AUFZEICHNUNGSMATERIAL. |
| 摘要 |
Disclosed is a magneto-optical recording material whose composition formula is indicated by (Co1-aMa)100-yRy where M denotes at least one element selected from the group consisting of elements of the platinum group and Fe, Ni, Nb, Cu, Ag, Al, B, Si and Ge; R denotes either at least two elements selected from the group consisting of Tb, Sm, Gd, Dy, Ho and Y or a single element selected from the group consisting of Tb, Gd, Dy and Ho; the value a satisfies 0<a</=0.5, while the value y satisfies 14</=y</=36 in terms of atomic percent; the material being substantially amorphous. A perpendicularly magnetized amorphous film made of this material is excellent in thermal stability, corrosion resistance etc., and affords a greater read output-to-noise ratio (C/N). |
