Abstract

A zinc-incorporated magnetite (Zn_0.16Fe_2.84O ₄) film was fabricated on a zinc oxide (ZnO)-coated glass substrate at a deposition rate of 450 nm/h by a simple immersion in an aqueous solution containing an iron (III) nitrate hydrate and dimethylamineborane at 323 K. The structural, electrical, and magnetic characterizations were performed with X-ray diffraction, X-ray photoelectron spectroscopy, a scanning electron microscope, a two-point probe resistivity tester, a vibrating sample magnetometer, and an ultrahigh-frequency permeability measuring system. The Zn_0.16Fe _2.84O₄ film had a spinel cubic structure of 0.8380 nm in the unit-cell parameter and showed magnetic properties of 378 emu/cc in saturation magnetization and 39 Oe in coercive force, a very high resistivity of 5.7 × 10⁶ Ω cm, and a higher permeability of around 400 at high frequencies up to 600 MHz.
