GdTbFeCo magnetic thin films were prepared onto glass substrates by RF magnetron sputtering system. The effect of sputtering power on the magneto-optical properties of the thin films was investigated. It is found that when the distance between the target and substrates, the sputtering power, sputtering pressure and thickness of the GdTbeFeCo thin films are 72 nm, 75 W, 0.5 Pa and 120 nm, respectively,the kerr rotation angle and coercivity that in the ...
