- The spin-glass transition in Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te epitaxial layers and bulk samples with 0.24 ≤ x ≤ 0.43 and in quantum well structures on the basis of Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te were investigated by means of optical spectroscopy. Reduction of dimensionality of Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te layers down to the quasi-two-dimensional case realized in Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te/Cd$\text{}_{1- y}$Mn$\text{}_{y}$Te heterostructures frustrates the spin-glass formation, which is in agreement with theoretical predictions. The spin-glass formation is also frustrated in the vicinity of interfaces between semimagnetic and nonmagnetic semiconductors in CdTe/Cd$\text{}_{1-x}$Mn$\text{}_{x}$Te quantum wells.
