Preparation of Zinc/Nickel Ferrite Nanostructures by DC Reactive Magnetron Sputtering
Abstract
In this work, zinc/nickel ferrite (ZnNiFe2O4) nanostructures were synthesized by co-sputtering of Zn, Ni and Fe targets in presence of oxygen. A dc sputtering system employing closed-field unbalanced magnetron was used for the preparation of these films. The structural and optical properties of the prepared films were introduced by XRD, EDX, SEM, AFM, FTIR and UV-visible spectroscopy. Results showed that these films are polycrystalline, highly pure, with average particle size of 20-25nm and average surface roughness of 0.465nm. Also, they showed high transmittance in the ultraviolet region and their transmittance decreased in the visible region and then increased in the infrared region. These nickel ferrite nanostructures were prepared at low production cost, high reliability and reasonable structural purity.
