We have demonstrated the feasibility of doping CdCr2Se4 single crystals with Group III elements (Ga, In, and Al) during annealing and identified relationships between annealing conditions, the composition of annealing mixtures, and properties of the crystals. Annealing mixture compositions have been found that ensure the possibility of preparing CdCr2Se4 single crystals with a considerably increased Curie temperature. We have performed multistep annealing of particular samples, which has made it possible to understand the role of each mixture component.
