GdTbFeCo magnetic thin films were prepared onto glass substrates by RF magnetron sputtering system. The effect of thickness on the magneto-optical properties of the thin films was investigated. Magnetic-optical characteristic measurement showed that when the sputtering power, sputtering pressure and thickness of the GdTbFeCo thin films are 75W, 0. 5Pa and 120nm,respectively,the kerr rotation angle and coercivity that in the perpendicular direction are as high as 0. 393° and 4575. 476Oe, respectively. These can satisfy the request of magnet...
