Faraday effects due to excitons in Cd1-xMnxTe films.

Abstract
Theoretical investigation has been performed on the Faraday effect of Cd1-xMnxTe epitaxial films prepared by ionized-cluster beam deposition technique. Splitting energies and oscillator strengths of an exciton level are calculated by taking account of a nondegenerate second order perturbation. The wavelength dispersion of the calculated Faraday rotation spectra is compared with the experimental data of Cd1-xMnxTe films. This suggests that the Faraday rotation is closely related to the magnetooptical transitions to Zeeman splitting levels of exciton.
