Abstract: The crystallographic parameters of CuIn₂Se₄ possessing a CdAl₂S₄-type crystal structure and Cu(In_1−xGa_x)₂Se₄ solid solutions based on it were determined. The evaluated magnetic properties confirmed the presence of copper(II) in the crystal lattices of CuIn₂Se₄ and Cu(In_0.7Ga_0.3)₂Se₄ solid solutions, which are semiconductors with band gaps of ≥1.08 and ≥1.17eV (at 298K), respectively, found from their cathodoluminescence spectra.
