We have collected the EPR spectra for Fe ions of zinc selenide single crystals in the temperature range from 5 to 300 K. The samples under test were grown by the Bridgman method and had a homogeneous structure of the ZnSe:Fe solid solution. Temperature-induced charge transfer from Fe3+ into Fe2+ on cooling is detected. The EPR spectrum formationmechanism is studied using a complex theoretical approach that combines the semi-empirical Modified Crystal Field Theory and structure optimizations using the DFT-based band-periodic plane-wave pseudopotential method.
