Abstract

We report on the magnetic properties of an oxide-diluted magnetic semiconductor (DMS), Zn0.64Mn0.36O. The temperature dependence of the magnetization shows a spin-glass behavior with the large magnitude of the Curie-Weiss temperature, corresponding to a stronger antiferromagnetic exchange coupling than other II-VI DMSs. The small effective Mn moment (x̄∼0.02) under high field also represents a strong antiferromagnetic exchange coupling in this compound.
