CONCENTRATION DEPENDENCE OF THE ZEEMAN SPLITTING OF EXCITON IN Zn1-xMnxTe AND Cd1-xMnxTe

Magnetoreflectivity and magnetization measurements were performed in Zn1-xMnxTe and Cd1-xMnxTe for 0.02 ≤x≤0.73 at 4.5 K in fields up to 5.5 T. Zeeman splitting versus average moment per cation is roughly linear for all x, but the slope decreases drastically at high x. A second-order perturbation calculation accounts for this decrease
