系统地研究了Cd_（1-x）Mn_xTe混晶（0 ≤ x ≤ 0.4）的光致发光谱随温度和磁场的变化。在激子区有两条发光线。第一条线是由激子结合到中性受体的复合引起的。详细的理论解释这条线给出的束缚磁极化子。对于第二条线，在自旋玻璃相变附近观察到温度依赖性曲线上的结构。这条线归因于激子的磁性局域化。
Systematic investigations of the photoluminescence spectra of Cd1-xMnxTe mixed crystals were performed for 0<or=x<or=0.4 as a function of temperature and magnetic field. Two luminescence lines are distinguished in the excitonic region. The first line is caused by recombination of excitons bound to neutral acceptors. A detailed theoretical interpretation of this line is given in terms of the bound magnetic polaron. For the second line a structure on the curve of temperature dependence is observed in the vicinity of the spin-glass phase transition. That line is attributed to a magnetic localisation of excitons.
