Abstract: A magnetic material includes a soft magnetic metal grain containing Fe, and a multilayer oxide film covering the surfaces of the soft magnetic metal grain. The multilayer oxide film has a first oxide layer of crystalline nature containing Fe, and a second oxide layer of amorphous nature containing Si. In an embodiment, the silicon oxide film of amorphous nature is formed by dripping, divided into multiple sessions, a treatment solution containing TEOS (tetraethoxy silane), ethanol, and water into a mixed solution containing the soft magnetic metal grain, ethanol, and ammonia water, to mix the solutions.

Abstract: A magnetoelectric multiferroic nanocomposite. The nanocomposite comprises a ferroelectric perovskite oxide and a rare-earth substituted mixed ternary transition metal ferrite of the formula A1−xBxRyFe2−yO4. The nanocomposite has a high dielectric constant, low dielectric loss, both stable over a wide frequency range. These properties may make the nanocomposite desirable for applications in microelectronic devices, sensors and antennas.
