Abstract :
In this paper the results of the electroresistivity measurements of ZnMn2As2 are presented. The temperature dependence ρ(T) reveals some anomalies in the region of the magnetic phase transitions. The calculated derivative dρ/dT shows λ-anomalies in the same temperature intervals. The derivative form near the critical points is in a good agreement with the theoretically predicted one. All these facts prove the relationship between the observed anomalies in ρ(T) and the magnetic phase transitions
