Abstract :
We have investigated the electron cyclotron resonance in the quantum Hall systems of II-VI semiconductors (Cd1-xMnxTe/CdMgTe quantum well) with the use of the THz and GHz frequency sources at steady high magnetic fields. Anomalous magnetic field dependence of the cyclotron resonance width originating in the localization of carriers has been observed in the CdMnTe/CdMgTe quantum well.
