摘要：

Studies of the optical, magnetic, and electrical properties of a CuFe2.33In9.67S17.33 single crystal in 5-300 K temperature and 0-14 T field ranges are carried out. The nature of the change of spectral dependence of the absorption coefficient is found. Bandgap is determined, which is equal 1.5 eV. It is established that the studied sample is paramagnetic. In the main state ferromagnetic correlations of a near order are found, which are characteristic for spin glass with a freezing temperature in an area of 9 K. The magnetic ordering temperature is about 11 K. The sample studied is a semiconductor with 15.2 k Omega.cm resistivity at room temperature. The magnetic and electrical states' formation mechanism for a CuFe2.33In9.67S17.33 single crystal is proposed.
