Modified ferrite plating of Fe3O4 and CuFe2O4 thin films

The present work proposes a modification of the ferrite plating method for synthesizing ferrite thin films from aqueous solutions at low temperatures about 97 degrees C. Our approach combines spin-splay deposition from aqueou s solutions at low temperature with co-precipitation. We were thus able to produce isotropic polycrystalline Fe3O4 and CuxFe3-xO4 films with thickness es from 100 to 1000 nm. The modified ferrite plating enabled us to produce CuFe-oxide films with cubic and tetragonal crystalline structure and Jahn-T eller effect have been observed. The spectra showed that the films of magne tite were isotropic while the heat-treated samples of CuxFe3-xO4 films show ed anisotropic behavior and coercivity of 1000 Oe.
