description: This work is devoted to the study of the relaxation mechanisms of photoexcitation in diluted magnetic semiconductors AII1-xMnxBIV in an external magnetic field in Faraday geometry at a temperature of 1.8 K by the polarized photoluminescence technique. The aim of the work is to experimentally study the phenomenon of the suppression of energy transfer from excitons to the excitation of intracenter d-d transitions of manganese ions in an external magnetic field and to compare the proposed model with the experiment. The goals of the work were to obtain intensity and polarization spectra of exciton photoluminescence and manganese intracenter photoluminescence of wide-gap diluted magnetic semiconductors Cd1-xMnxTe (x = 0.40) and Zn1-xMnxSe (x = 0.01) depending on the external magnetic field and the phase state of the sample (spin-glass or paramagnetic); analysis of the total integral intensity of exciton luminescence and manganese intracenter d-d photoluminescence; analysis of the results. The experimental results gave a good agreement with the theoretical model proposed in literature. It is shown that the mechanism of energy transfer from excitons to manganese ions is equally effective both in a paramagnetic system and in a spin glass, and is equally sensitive to an external magnetic field. Anti-Stokes exciton photoluminescence was detected during the resonant photoexcitation of manganese d-d transitions in Cd1-xMnxTe (x = 0.40), which is associated with a two-stage process of light absorption by a manganese ion followed by energy transfer to the exciton by an Augertype mechanism. This work is aimed at fundamental research, but nevertheless, it is of practical interest for spintronics applications.
