Abstract
The magnetic and magneto-optical properties of a Cr-doped II-VI semiconductor ZnTe were investigated. Magnetic circular dichroism measurements showed a strong interaction between the carriers and localized spins, indicating that is a diluted magnetic semiconductor. The Curie temperature of the film with was estimated to be , which is the highest value ever reported for a diluted magnetic semiconductor in which interactions were confirmed. In spite of its high Curie temperature, film shows semiconducting electrical transport properties.
