Ultrahigh magnetic fields of up to 500 T have been used for investigations of the Faraday effect in the dilute magnetic semiconductor Cd1-xMnxTe. Measurements have been carried out using samples of the content x=0.43 at wavelengths 0.63 and 1.06 μm at room temperature. Magnetic field dependence of the Faraday rotation is linear at both wavelengths up to 100 T. At higher fields there is a saturation in this dependence which has been interpreted as arising from a change of magnetization in the ensemble of Mn2+ ions. It is shown that it is necessary to consider the interband exchange interaction and the direct influence of the external magnetic field on the carrier spins for correct interpretation of the experimental results
