Abstract

Magnetization and magnetoreflectivity studies of two Zn 1-xCoxSe epilayers (x=0.0076 and 0.0104) were carried out. These experiments yield a value for the exchange parameter difference N 0(α-β)=2420±40 meV, which is significantly higher than the values observed in other diluted magnetic semiconductors. The study verified that ZnCoSe is a Brillouin paramagnet.
