The single crystals of Sb and V doped zinc chromium selenide spinel ZnCrSe were prepared by a chemical transport method and characterized by ESR spectroscopy in order to examine an effect of nonmagnetic antimony and magnetic vanadium on a properties of the system. For antimony admixtures the Neel temperature is very similar to that of the parent spinel ZnCrSe (22K). However, upon incorporating vanadium ions, the T temperature decreases down to 17.5K, determined for the maximum vanadium content (x=0.06). The temperature dependence of the ESR linewidth over paramagnetic region is interpreted by an occurence of spin-phonon interaction. The strong broadening linewidth together with its strong temperature dependence for vanadium doped ZnCrSe is explained by the complex paramagnetic relaxation model.
