Abstract:

Cu0.4 Zn0.6Fe2O4 Nano ferrite is prepared using Citrate-nitrate sol-gel auto combustion method. Dielectric properties such as dielectric constant and dielectric loss factor are reported for Cu0.4 Zn0.6Fe2O4 ferrite. The variation of dielectric constant and dielectric loss with frequency are measured in the frequency range 100 Hz to 120 MHz at room temperature. Dielectric constant as a function of temperature is studied at different temperatures ranging from 303 K to 500 K using a Wayn Kerr 6500B Precision impedance analyzer. The crystal structure and grain size of the particles are studied using XRD .
