ABSTRACT
We report on the magnetic properties of an oxide-diluted magnetic semiconductor (DMS), Zn[sub 0.64]Mn[sub 0.36]O. 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 (x¯∼0.02) under high field also represents a strong antiferromagnetic exchange coupling in this compound. © 2001 American Institute of Physics.
