Title:
SOFT MAGNETIC ALLOY, POWDER-COMPACT MAGNETIC CORE, AND MAGNETIC COMPONENT
Document Type and Number:
Japanese Patent JP2023062497
Kind Code:
A
Abstract:
To provide a soft magnetic alloy, a powder-compact magnetic core and a magnetic component that can realize a high withstand voltage and a high m value.SOLUTION: Provided is a soft magnetic alloy having a body portion having a soft magnetic alloy composition containing Fe and Co, and a surface layer portion located on the surface side of the body portion. Setting the ratio of the Co concentration to the sum of the Co concentration and the Fe concentration in the surface layer portion as Co/(Fe+Co), the distribution of Co/(Fe+Co) in the thickness direction of the surface layer portion has a minimum point and at least 1 or more maximum points.SELECTED DRAWING: Figure 2B
