Abstract :
In this paper, ferromagnetic diluted magnetic semiconductors (DMSs) have exchange interaction between sp-carriers and localized d-spins (sp-d exchange interaction). The sp-d exchange interaction can be detected directly only by the magneto-optical measurements such as a magnetic circular dichorism (MCD) spectroscopy. Recently, we confirmed the sp-d exchange interaction in a ferromagnetic Zn1-xCrxTe (x=0.20) film of which Curie temperature Tc was 300K.
