Abstract    Applying Bridgman method it was obtained that tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc. Measurements of the temperature dependence of conductivity and magnetoresistance in the temperature range of 1.6K to 300K and in magnetic field up to 25 T were carried out. Close to helium temperatures it is set to a range of implementation of Mott\\\'s variable-range hopping conductivity mechanism. It was determined that the width of the coulomb D = 0.21 meV and a rigid gap δ = 0.026 meV in the density of localized states, concentration and localization radius of charge carriers.


Keywords    single crystals, solid solutions, hopping conductivity, Dirac semimetal.
