采用射频磁控溅射法在玻璃基片上成功制得了GdTbFeCo非晶垂直磁化膜,研究了溅射工艺对GdTbFeCo薄膜磁光性能的影响.测量结果表明,基片与靶间距为72mm,溅射功率为75W,溅射气压为0.5Pa,薄膜厚度为120nm时,GdTbFeCo薄膜垂直方向矫顽力为477.6kA/m,克尔角为0.413°.
GdTbFeCo magnetic thin films were prepared onto glass substrates by RF magnetron sputtering system. The effect of sputtering parameters on the magneto-optical properties of thin films were investigated. It is found that when the distance between the target and substrates, the sputtering power, sputtering pressure and thickness of the GdTbFeCo thin films are 72mm, 75W,0. 5Pa and 120nm,respectively,the Kerr rotation angle and coercivity that in the perpendicular direction are as high as 0. 413°and 6477. 6kA/m.
