Abstract
Cu x Zn1−x Fe2O4 samples exhibit dispersion of dielectric constant, tanδ and resistivity in the frequency range of 1 kHz to 50 MHz. The dispersion exhibited is in general accord with Koops’ model. However, the details of the conducting and non-conducting regions must be taken into account when composition tends to change interrelationship between the elementary capacitor resistor circuits.
On quenching these samples from 800°C the dielectric constantε 1 showed an increase for CuFe2O4 and Cu0·8Zn0·2Fe2O4 samples. The dielectric constant of the remaining samples showed no influence on quenching. The compositional variation showed that the dielectric constant has higher value for the ferrite Cu0·4Zn0·6Fe2O4
The results are explained on the basis of cation transfer.
