Abstract
Optical path modulation-an interference-based photoreflectance method- is used to study the influence of magnetic properties on the band stru cture of Cd1-xMnxTe. The results obtained due to the extreme sensitivi ty of this interferometric method indicate a renormalization of the ef fective mass under the influence of magnetic fluctuations, not observe d so far. Time-dependent measurements supply additional arguments for the thermomagnetic character of the modulation and allow one to study magnetic relaxation phenomena. [S0163-1829(98)01012-1].
