摘要：

Amorphous Tb-Fe based thin films of Tb-Fe, TbGd-Fe and Tb-FeCo have been investigated for magnetooptical recording media. The films were deposited by using a two-source dc-sputtering method. The magnetic and magneto-optical properties of the films were investigated as a function of composition and it was found that the films with low rare-earth composition had perpendicular magnetization and showed a high squareness of hysteresis loop. In magneto-optical recording on the Tb-Fe based thin films deposited on plastic disks, a high carrier-to-noise ratio was obtained over a wide frequency range. The recording of FM video signal has been made possible on these high C/N disks.
