Аннотация: This work is a report of the present authors' experimental results on the synthesis and investigation of thin films of the chalcogenide chromium spinels CdCr2Se4, CuCr2Se4 and CuCr2Te4. Films were made by the method of vacuum condensation from separate sources. As substrates glass, mica, MgO, CaF2, Y2O3 and NaCl were used. With the last of these vacuum condensation results in the formation of a single-crystal film CdCr2Se4, the physical characteristics of which are, however, worse than those of polycrystalline films. The measured temperature dependences of magnetization, ferromagnetic resonance and electron paramagnetic resonance linewidths, electric resistance and magnetic conductivity are given. We have realized and investigated stripe domain structures in CdCr2Se4. Photoelectric, photomagnetic and magneto-optical properties are studied. The magnetic and electric characteristics of stoichiometric polycrystalline films are close to those of bulk materials. The effects of diffuse substitution with indium, gallium (donors) and silver, copper (acceptors) and of non-stoichiometry on the magnetic and electric properties of CdCr2Se4 semiconductor films are investigated.
