紫蓝磁光材料的量子法拉第效应

Effects of Quantum Faraday in Violet and Blue Light Magneto optical Materials

从量子角度分析了Ｂｉ３＋离子替代对紫蓝磁光材料法拉第效应的影响，研究了ＤｙＩＧ（镝铁石榴石）材料的磁光频谱特性，结果表明ＤｙＩＧ材料在３５０ｍｍ和５５０ｎｍ有两个磁光极大峰值，这极有利于短波高密度磁光记录。

The effects of Bi substitution on the faraday angle of violet and blue light magneto optical materials are studied by using the quantum theory method.The curves of faraday angle as a function of frequence are analzed.The results show that the DyIG materials have two peak valves in 350 nm and 550 nm,which is very useful for the high density MO recording.
