Abstract :
Magneto-optical properties in the visible wavelength region are studied on CdMnTe films grown on quartz glass and sapphire (0001) single crystal substrates by MBE. Good quality films with sharp spectra of X-ray diffraction are obtained on the sapphire substrates polished carefully and pre-heated up to 950°C. Weak (111) film-growth is observed for films deposited on the quartz glass substrates. A value of Faraday rotation angle of -0.31 deg/cmG at 700 nm is measured in the Cd 0.59Mn0.41Te film grown on the sapphire substrate. The values for the films on the quartz glass substrates are 1/3 of those on sapphire. It is shown that the specific rotation in CdMnTe depends strongly upon the crystalline quality of films deposited on the substrate
