Modified ferrite plating of Fe3O4 and CuFe2O4 thin films

Abstract The present work proposes a modification of the ferrite plating method for synthesizing ferrite thin films from aqueous solutions at low temperatures about 97°C. Our approach combines spin-spray deposition from aqueous solutions at low temperature with co-precipitation. We were thus able to produce isotropic polycrystalline Fe 3 O 4 and Cu x Fe 3− x O 4 films with thicknesses from 100 to 1000 nm. The modified ferrite plating enabled us to produce CuFe-oxide films with cubic and tetragonal crystalline structure and Jahn–Teller effect have been observed. The spectra showed that the films of magnetite were isotropic while the heat-treated samples of Cu x Fe 3− x O 4 films showed anisotropic behavior and coercivity of 1000 Oe.
