Аннотация:Optical absorption in MnGaInS4 single crystals has been studied. Direct and indirect optical transitions are found to occur in the range of photon energies of 2.37-2.74 eV and in the temperature range of 83-270 K. The temperature dependence of the band gap has been determined; its temperature coefficients E-gd and E-gi are -5.06 x 10(-4) and -5.35 x 10(-4) eV/K, respectively. MnGaInS4 single crystals exhibit anisotropy in polarized light at the absorption edge; the nature of this anisotropy is explained.
