Magnetic properties of [FeCo-O/NiZn-Ferrite]n bi-magnetic phase nanocomposite multilayer films

Abstract

[FeCo-O/NiZn-Ferrite]n multilayer films with different thicknesses of FeCo-O and NiZn-Ferrite layer were fabricated by alternant magnetron sputtering at room temperature with no external magnetic field applied. The effect of monolayer thickness on magnetic and high frequency characteristics was systematically investigated. The multilayer thin film could acquire excellent high-frequency properties and high resistivity when the thickness of FeCo-O layer and NiZn-Ferrite layer was 2nm and 2.1nm respectively, which makes these multilayer films great candidates as magnetic core for microinductor.
