Abstract
Large-block crystals of FeIn2S4, MnIn2S4 ternary compounds and MnxFe1–xIn2S4 solid solutions are grown by the method of directional crystallization (horizontal Bridgman method). The structure of the obtained crystals is determined by X-ray diffraction analysis. It is shown that both the starting compounds and solid solutions based on them crystallize in the cubic spinel structure. The IR reflection spectra in the frequency range 50–500 cm–1 of crystals of ternary compounds FeIn2S4, MnIn2S4 and solid solutions MnxFe1–xIn2S4 are studied. The frequencies of transverse (ωTO) and longitudinal (ωLO) optical phonons are determined. The concentration dependences of these parameters are plotted and the nature of their behavior is established
