We newly prepared two types of DMS films deposited on quartz glass substrates by molecular beam epitaxy (MBE). The compositions of the DMS films are ZnMnTe and ZnMnSe. To determine the basic characteristics of these DMS films, we evaluated their transparency and Faraday rotation, and evaluated the ac magneto-optical properties at 1.6 kHz. Finally, we discussed the potential of these DMS films in the development of applications such as optical CT.
