采用单离子晶格模型，以磁光量子理论计算了Bi 3+、Ce3+离子替代的稀土铁石榴石晶体中Bi3+、Ce3+离子的晶场能级，波函数及能态间电偶极跃迁几率，进而计算了Bi3+、Ce3+离子对法拉第旋转角θF的贡献，获得了与实验符合较好的计算结果，加深了对Bi3+、Ce 3+离子极大增强铁石榴石磁光效应微观机制的认识。

The split energy levels,occupation probabili ties,wave function and electrical dipole transition induced by crystal field and exchange interaction for the Ce3+ ions in Ce3+-substituted and the Bi3+ ions in Bi3+-substituted iron garnets at room temperature bas ed on quantum theory has been calculated.Furthermore,the calculation of the Fara day rotation contributed by the Ce3+ and Bi3+ ions has also been car ried out.The crystal field and the super-exchange interaction are two crucial f actors in determining the Faraday rotation.The theoretical results are in good t hose of experiments.
