摘要：
The electrical conductivity of polycrystalline mixed ferrite system having the chemical formula MnxZn1-xFe2O4 (where x = 0.0, 0.2, 0.4, 0.6, and 0.8) was investigated from room temperature to the neighborhood of the Curie temperature by the two-probe method. The electrical conduction in these ferrites is explained on the basis of the hopping mechanism. Plots of log (sigmaT) verSUS 10(3)/T are almost linear and show a transition near the Curie temperature. The activation energy in the ferrimagnetic region is in general less than that in the paramagnetic region.
