摘　　要：采用磁控溅射复合靶的方法制备了SmTbCo/Cr和SmDyCo/Cr非晶垂直磁化膜,分析了Sm含量对SmTbCo/Cr和SmDyCo/Cr薄膜磁光性能的影响.结果表明：随着Sm含量的增加,（SmxTb1-x）31 Co69和（SmxDy1-x）36 Co64薄膜的剩余磁化强度Ms、克尔旋转角θk和反射系数R增加,而Hc随之减少;Sm含量为29%～30%时,Hc×Ms最大.The amorphous SmTbCo/Cr and SmDyCo/Cr films with perpendicular anisotropy has been prepared by magnetron sputtering of complex target. The Srn Composition effects on the magneto- optical properties of SmTbCo/Cr and SmDyCo/Cr films are analyzed. The results show that the Ms, 6k and R increase in the （SmxTb（1-x）31 Co69 and （SmxDy1-x）36 Co64 films with the increase in Sm Composition, but the Hc decreases. When the Sm Composition is in 29 % -30 %, the Hc×Ms is maximum.
