通过在6.5T下对σ和π光偏振进行的磁反射实验研究了Zn 1− xMn xTe（x< 0.5）中自由激子态的交换分裂。磁化强度测量高达15 T确定的Mn 2+自旋沿着磁场的平均值。在1.86K下，在顺磁区（x≤ 0.17），对相同样品的磁光数据和磁数据进行了比较，结果表明与简单交换相互作用模型非常吻合，并给出了Mn 2+离子与传导电子和价电子的交换积分的精确值（分别为-0.18和1.05eV）。还描述了磁化数据的拟合。
The exchange splitting of the free-exciton state in Zn 1− x Mn x Te (x< 0.5) is studied by magnetoreflectance experiments carried out up to 6.5 T, for σ and π light polarization. Magnetization measurements made up to 15 T determine the mean value of the Mn 2+ spins along the magnetic field. Comparison of magneto-optical with magnetic data, obtained for the same samples, at 1.86 K, in the paramagnetic region (x≤ 0.17) shows an excellent agreement with the simple exchange interaction model and yields precise values of exchange integrals of Mn 2+ ions with conduction and valence electrons (-0.18 and 1.05 eV respectively). Fits of the magnetization data are also described.
