Abstract :
To fabricate ferrite films, electrophoretic deposition (EPD) of magnetite fine particles, synthesized by Fe2+→Fe3+ oxidation, in water dispersion mixtures was carried out at room temperature. It is shown that densely packed ferrite films with a thickness of 9.2 μm can be deposited via EPD from magnetite fine particles with a size of 10-30 nm onto a copper substrate. The film exhibited soft magnetic properties almost the same as raw magnetite particles.
