摘　　要：首先介绍了磁性石榴石的晶体结构和元素替代理论,然后重点介绍了Bi:YIG与Ce:YIG薄膜的制备方法和磁光特性。降低吸收损耗和增大Ce、Bi离子含量可以增大石榴石薄膜的磁光优值。薄膜良好的磁光性能依赖于合理的制备工艺。Ce-,Bi-YIG是制备磁光波导器件的良好材料。This paper first introduces the crystal structure and theory of cations substitution of magnetic garnets. The preparation methods and magneto-optical characteristics of Bi：YIG and Ce：YIG thin films are emphatically discussed. Reducing propagation loss and increasing Ce^3＋, Bi^3＋ content can enlarge the figure of merit. Excellent magneto-optical properties depend on rational preparation condition. Ce-, Bi-YIG arc good materials for waveguide devices.
