Аннотация:This paper presents the results of a study of the effect of a strong electric field on the electrical properties of MnGaInS4 : Eu single crystals. The compound was obtained by the Bridgman method and consists of plane-parallel layered plates. The following parameters are determined on the basis of these studies : concentration of trap levels 10(13)-10(14) cm(-3) and activation energy 0.70-0.50 eV. It is established that the conductivity of MnGaInS4 : Eu increases in strong electric fields mainly because the current-carrier concentration increases with electric field.
