摘要：
Magneto-optical properties of semimagnetic semiconductors with nanometer-scale structures (nanostructures) are described. Superlattices of the CdTe/Cd1-xMnxTe and Cd1-xMnxTe/ZnTe systems and microcrystals of Cd1-xMnxSe were grown by epitaxy and sputtering methods. These semimagnetic semiconductor nanostructures show remarkably enhanced magneto-optical responses in the optical absorption, the luminescence and the dynamics of the confined excitons. The results are interpreted by the quantum-confined excitonic states interacting with the magnetic ion spins involved in the nanostructures.
