MAGNETIC RIBBON AND MAGNETIC CORE USING SAME

Title:

MAGNETIC RIBBON AND MAGNETIC CORE USING SAME

Document Type and Number:

WIPO Patent Application WO/2021/049554

Kind Code:

A1

Abstract:

In a magnetic ribbon (1) of an embodiment, when XRD analysis of a Fe-Nb-Cu-Si-B magnetic ribbon is performed, the crystallinity represented by the total crystal phase peak area/(amorphous phase peak area + total crystal phase peak area) is 0.05-0.4. When EBSD analysis of the crystal phase is performed, the magnetic ribbon (1) preferably has a region in which a Kikuchi pattern is detected. The magnetic ribbon also preferably has a thickness of not more than 25 μm.
