Abstract

The Faraday rotation of Cd_0.8Mn_0.2Te and Cd_0.9Mn_0.1Te 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 (E₁) and obtained the values of the gap at the Γ point in the Brillouin zone (E₀) for Cd_0.8Mn_0.2Te and Cd_0.9Mn_0.1Te from the fitting to 1.667 eV and 1.804 eV, respectively. The values of E₀ are more close to the calculated ones than nearly all of the previous studies.
