Title:
MAGNETIC COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2022/154058
Kind Code:
A1
Abstract:
Provided is a magnetic composite comprising a ferrite layer which is dense, has a relatively thick film thickness, exhibits excellent magnetic properties and electric properties, and has good adhesion. The magnetic composite comprises a metal substrate and a ferrite layer provided on a surface of the metal substrate. The metal substrate has a thickness (dM) greater than or equal to 20 μm. The ferrite layer has a thickness (dF) greater than or equal to 2.0 μm and is based on a spinel-type ferrite, wherein a ratio (I222/I311) of an integrated intensity on (222) plane (I222) to an integrated intensity (I311) on (311) plane according to X-ray diffraction analysis is 0.00 to 0.03 inclusive.
