Abstract: The quenching of photoluminescence in a ZnSSe layer with an increase in the Cr concentration has been investigated in heterostructures with ZnSSe: Cr/ZnMgSSe quantum wells. It has been found that an increase in the Cr concentration in the quantum well to 2 $\times$ 10$^{20}$ cm$^{-3}$ leads to the formation of two types of magnetically ordered nanoclusters of chromium alloys in the ZnSSe: Cr layer with the magnetization blocking temperature of 170 K and above 300 K.
