Аннотация:Current-voltage (I-V) characteristics I(U) of MnIn2S4 and MnGa2S4 single crystals are studied in the dark and under exposure to light. The I-V characteristic of the MnIn2S4 single crystal contains I proportional to U, I proportional to U-2, and I proportional to U-3 portions in the dark and I proportional to U, I proportional to U-3/2, and I proportional to U-2.5 portions under exposure to light. It is shown that the current under exposure to light exceeds the current in the dark by a factor of almost 10(4). In the MnGa2S4 single crystals exposed to light, the I-V characteristic has I proportional to U and I proportional to U-3/2 portions. An interpretation is given for these dependences.
