AB  - The frequency and temperature dependences of the tangent of dielectric
      loss angle as well as the real and imaginary part of the dielectric
      constant of MnGaInTe4 crystals are investigated in the frequency range
      of 102 to 106 Hz. The experimental values of the studied characteristics
      are determined. The real and imaginary parts of the permittivity are
      found to undergo significant dispersion, which has a relaxation nature.
      The main type of dielectric losses in MnGaInTe4 crystals in the
      frequency range of 102 to 106 Hz are the electrical conductivity losses.
      The conductivity is characterized by a zone-hopping mechanism. The
      activation energies of charge carriers are determined.
