Abstract
Co-precipitation technique using chlorides of constituents was used to prepare fine particles Ni-Zn ferrites. The particle size was estimated from X-ray diffraction data using Sherrer's formula. The dc electrical resistivity and thermo-power was measured in the temperature range 300-450 K and it was found that all the samples are degenerate type semi-conductors. The results of dc resistivity and thermo-electric power confirm that the conduction mechanism in these ferrites is due to small polaron hopping.
