Title:
MAGNETIC COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2022/172939
Kind Code:
A1
Abstract:
Provided is a magnetic composite comprising a ferrite layer that is dense, has a relatively thick film thickness, exhibits excellent magnetic properties and electric properties, and has good adhesion.　The magnetic composite comprises a resin substrate and a ferrite layer provided on a surface of the resin substrate. The resin substrate has a thickness (dR) greater than or equal to 10 μm. The ferrite layer has a thickness (dF) greater than or equal to 2.0 μm and is based on a spinel-type ferrite. The ratio (I222/I311) of an integrated intensity (I222) on a (222) plane to an integrated intensity (I311) on a (311) plane according to X-ray diffraction analysis is 0.00 to 0.03 (inclusive).
