研究了用射频磁控溅射法制备的GdCo/TbFe和GdTbCoFe/TbFe多层非晶薄膜的磁性和磁光克尔效应。溅射结果表明：当多层膜中两层膜间TM原子的磁矩方向相反时，观察到反常的磁克尔旋转磁滞回线，但随着GdCo层厚度的增加，磁克尔旋转磁滞回线变为正常的磁滞回线。而在TM原子磁矩平行排列的多层膜中，磁滞回线的行为与单层膜的情况类似，且θk随GdCo或GdTbCoFe层厚度的增加而单调增加。
Magnetic properties and the magneto-optical Kerr effect were investigated in the multilayered amorphous GdCo/TbFe and GdTbCoFe/TbFe films prepared by R.F. sputtering. As a result, the following have been clarified: In the case of the multi-layered films in which the magnetic moments of TM atoms between two films arrange oppositely with each other, anomalous magnetic Kerr rotation hysteresis loops are observed but they become normal loops with increasing film thickness of GdCo layer. On the other hand, in the multilayered films with parallel arrangement of TM atom moments, the behavior of hysteresis loops is analogous to the case of single layered film, moreover θk increases monotonically with the increasing film thickness of GdCo or GdTbCoFe layer.
