摘要：

The near-infrared Faraday rotation of Cd1-xMnxTe has been measured for x = 0-0.3 at 300 and 77 K for photon energies between 0.1 (12.0) and 1.5 (0.8) eV (mu-m). We have developed a multioscillator model for the Faraday rotation using an analytical expression for the refractive index that includes contributions from interband transitions at the GAMMA, L, and X points of the Brillouin zone, as well as the lattice contribution from optical phonons. The multioscillator model explains the measured behavior of the Verdet constant as a function of photon energy for all concentrations at both temperatures. This model has also been applied successfully to Faraday rotation data for Cd1-xMnxTe and Zn1-xMnxTe from previous studies.
