摘　　要：在半磁半导体Cd_(1-x)Mn_xTe中实现了不需改变施加磁场方向的新型磁光开关效应,该效应是由Cd_(1-x)Mn_xTe的巨大法拉弟效应和磁光反馈系统的饱和特性产生的。讨论了该效应用于光控、温控磁光开关及混合型磁光光学双稳态的可能性。A new class of magneto-optical switch effect, which does not require to change the direction of the magentic field applied to the sample, was realized in the semimagnetic semiconductor Cd_(1-x)Mn_xTe. This effect was due to the giant Faraday effect of Cd_(1-x)Mn_xTe and the saturation characteristic of the magneto-optical feedback system. The possible applications of the magneto-optical switch for optical and temperature control, and the possibility for realizing the magneto-optical bistability are discussed in this paper..
