摘要：

Wavelength, magnetic field, and temperature dependences of Faraday rotation (FR) in various compositions of the dilute magnetic semiconductors Cd1-xMn Te and Zn1-xMn Te have been experimentally investigated. Regularities of the Faraday effect dispersion connected with the change of rotation direction as a function of temperature and Mn concentration in the compound have been revealed. Deviation in FR saturation at helium temperatures and high magnetic fields is observed. According to the FR temperature dependence, the spontaneous Faraday effect is assumed to be a characteristic of the spin glass state of semimagnetic semiconductors. A rapid magnetic field sensor system as a possible application of this material has been proposed. © 1990.
