Physical properties of Ba2Nl2-xZnxFe12O22 hexaferrites

The effect of composition on the structure, electrical conductivity, dielectric behavior, initial magnetic permeability and thermoelectric power for a series of Y-type Ba2Ni2-xZnxFe12O22 hexaferrite samples prepared using the usual ceramic was studied. The frequency dependence of electrical conductivity and dielectric behavior was discussed. The study gives much more valuable information on the behavior of free and localized electric charge carriers. It leads to a comprehensive explanation of the mechanisms of electric conduction and dielectric behavior in the studied samples.
