Abstract

Diluted magnetic semiconductors offer the unique medium for the study of semiconductor physics and magnetism through the electron-ion exchange interaction. Precisely controlled heterostructures alter the band structure, the interaction scheme and the dimensionality, affecting both the underlying electronics and magnetics. Focusing on the typical system of CdTe-CdMnTe, we have used static and dynamic techniques to pursue optical and magnetic properties from luminescence, spin-polarization and magnetization experiments. We present results of the dimensional effect on electric confinement and magnetic interaction, as well as spin exchange and relaxation of the electronic and ionic systems.
