摘要：

The mid and near infrared (115-1165meV) complex Faraday and Kerr effects are studied in a Ga1-xMnxAs random alloy film (x=0.05 and Curie temperature of 100 K) as a function of frequency and temperature. The strong infrared magneto-optical response shows clear ferromagnetic behavior that is consistent with de magnetization measurements. The real and imaginary parts of the measured Faraday and Kerr angles are in qualitative and quantitative agreement with the values predicted by effective Hamiltonian models within a mean field treatment.(1) Strong features in the Kerr and Faraday effects, with a peak rotation angle at around 5.5 mu m (220 meV) is observed consistent with theoretical predictions
