PHYSICAL PROPERTIES OF CuFe2.33In9.67S17.33 SINGLE CRYSTAL

The CuFe2.33In9.67S17.33 single crystals have been grown by the Bridgman method. The optical, magnetic and electrical properties investigations for this single crystal are carried out in 5 - 300 K temperature and 0 - 14 T magnetic field ranges. The variation of the spectral dependence of the absorption coefficient has been found. The band gap has been determined which is 1.5 eV. It is established that the sample studied is paramagnet. In ground state the ferromagnetic correlations of the short-range order typical for the spin glass with freezing temperature in range of 9 K are detected. The magnetic ordering temperature is almost 11 K. The sample studied is semiconductor with 15.2 kΩ*cm resistivity at room temperature. The magnetic and electrical states formation mechanism for the CuFe2.33In9.67S17.33 single crystal is proposed.
