<p>Nanocrystalline spinel copper ferrite CuFe₂O₄ thin film has been studied and synthesized via the electrodeposition-anodization process. Electrodeposited CuFe₂ alloys were obtained from aqueous sulphate bath. The formed alloys were electro oxidized (anodized) in aqueous (1 M KOH) solution, at room temperature, to the corresponding hydroxides. The anodized CuFe₂ alloy films were annealed in air at 400 ⁰C for 2 h. The parameters controlling of the electrodeposition of CuFe₂ alloys such as the bath temperature, agitation and the current density were studied and optimized. The crystal structure, crystal size and microstructure of the produced ferrites were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD shows that CuFe₂O₄ had a spinel structure and the crystallite size of CuFe₂O₄ phase was 2 nm.  SEM micrograph of the formed ferrite particles shows agglomeration structure morphology with a narrow distribution of the particles.</p>
