Abstract

Official abstract text for this publication.

A soft magnetic alloy including an internal area having a soft magnetic type alloy composition including Fe and Co, a Co concentrated area existing closer to a surface side than the internal area and having a higher Co concentration than in the internal area, and a Co concentration degree of the Co concentrated area is larger than 1.2.

First claim

Opening claim text (preview).

What is claimed is: 1. A soft magnetic alloy comprising an internal area having a soft magnetic alloy composition including Fe and Co, and a Co concentrated area existing closer to a surface side than the internal area and having a higher Co concentration than in the internal area, wherein a ratio of a Co concentration in the Co concentrated area to a Co concentration in the internal area is 1.25 or more, in which each of the Co concentration in the Co concentrated area and the Co concentration in the internal area is a mole ratio of Co with respect to a sum of Fe and Co, and the internal area is an area at a depth of 0.2 μm or more from an outermost surface of the soft magnetic alloy towards an inside. 2. The soft magnetic alloy according to claim 1 , wherein the Co concentrated area comprises a metal phase. 3. The soft magnetic alloy according to claim 1 having an amorphous degree of 85% or more. 4. The soft magnetic alloy according to claim 1 being a ribbon form. 5. The soft magnetic alloy according to claim 1 being a powder form. 6. A magnetic component including a soft magnetic alloy according to claim 1 .
