Study of Electrical and Magnetic Properties of Zn-Co-Ferrite Nanocomposites

The ferromagnetic material exhibits better magnetic properties as compared to other magnetic materials. Cobalt and ferrites have superior soft magnetic properties such as high permeability and magnetic susceptibility. A nanocomposite is prepared using Zinc, Cobalt and Ferrite by combustion synthesis method and the composition is Fe0.5Co0.25Zn0.25. The morphological properties are studied using FESEM images and XRD. The electrical and magnetic properties are studied from 10 Hz to 8 MHz frequency range using LCR meter at ambient temperature. The results show that with increase in frequency, the resistivity as well as permeability decreases. The values of electrical resistivity and dielectric constant suggest the suitability of the nanocomposites in power electronics devices.
