Title:
MAGNETIC POWDER MATERIAL, MAGNETIC DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/006124
Kind Code:
A1
Abstract:
The present application provides a magnetic powder material, a magnetic device, and an electronic device. The interior of a magnetic powder material particle comprises two or more magnetic layers. An insulating layer is contained between any two adjacent magnetic layers. The magnetic layer comprises a soft magnetic metal material; the insulating layer comprises an insulating material. The magnetic powder material provided by the present application can effectively suppress an eddy current effect generated in the particles of a high-frequency alternating magnetic field, thereby reducing the high-frequency eddy current loss and improving the high-frequency magnetic permeability.
