Magnetic behaviors of MnxFe3−xO4 thin films grown by ferrite plating method

We have performed ferrite plating of MnxFe3−xO4 (x=0.016, 0.028, 0.049, 0.066 and 0.090) films grown on the cover glass at substrate temperature range 75-90 °C and the fixed pH of the oxidizing solution, 7.1. The deposition rate and the saturated magnetization of thin film increased with the substrate temperature and X-ray diffraction (XRD) patterns of the films showed a single phase of polycrystalline spinel structure. The highest value, 506, of the saturation magnetization was obtained in the MnxFe3−xO4 film made at the substrate temperature 85 °C. The thickness and grain size of the film increased with the substrate temperature. On the other hand, the coercive force decreased with the increase of thickness and grain size of the film.
