Abstract :
The Faraday effect in Cd1-xMnxTe films prepared by ionized-cluster beams has been analyzed theoretically. Faraday rotation spectra are calculated taking account of a broadening parameter ¿ of exciton absorption in a nondegenerate second-order perturbation theory. The calculated spectra are compared with the experimental data of Cd1-xMnxTe films. The results reveal that the thermal broadening of exciton absorption is due to the scattering of an exciton by longitudinal optical (LO) phonons.
