摘要：
The Faraday rotation of Cd0.8Mn0.2Te and Cd0.9Mn0.1Te single crystals grown in our laboratory was measured at room temperature. We analyzed our Faraday rotation data in terms of a modified multi-oscillator model by improving the value of the band gap at L point in the Brillouin zone (E-1) and obtained the values of the gap at the Gamma point in the Brillouin zone (E-0) for Cd0.8Mn0.2Te and Cd0.9Mn0.1Te from the fitting to 1.667 eV and 1.804 eV, respectively. The values of E-0 are more close to the calculated ones than nearly all of the previous studies.
