Abstract
Official abstract text for this publication.
A soft magnetic body includes soft magnetic particles containing an element M and an intergranular region that exists between the soft magnetic particles and covers an outer periphery of the soft magnetic particles. On a cross-section of the soft magnetic body, a ratio of the element M at the center of the soft magnetic particles to a ratio of the element M in a soft magnetic composition that constitutes the soft magnetic body is within a range of 10% to 70%. On the cross-section of the soft magnetic body, an average of peripheral lengths of a plurality of the intergranular regions existing at the periphery of the soft magnetic particles is within a range of 5 μm to 15.5 μm.
First claim
Opening claim text (preview).
What is claimed is: 1 . A soft magnetic body comprising: soft magnetic particles containing an element M; and an intergranular region existing between the soft magnetic particles and covering the soft magnetic particles, wherein a ratio of the element M at the center of the soft magnetic particles to a ratio of the element M in a soft magnetic composition that constitutes the soft magnetic body is within a range of 10% to 70% on a cross-section of the soft magnetic body, and an average of peripheral lengths of the intergranular regions existing around each of the soft magnetic particles is within a range of 5 μm to 15.5 μm on the cross-section of the soft magnetic body. 2 . The soft magnetic body according to claim 1 , wherein the element M contains at least one or more elements of which ionization tendency is larger than ionization tendency of Fe and Si. 3 . The soft magnetic body according to claim 1 , wherein a ratio of the element M contained in the intergranular regions is higher than a ratio of the element M at the center of the soft magnetic particles. 4 . The soft magnetic body according to claim 1 , wherein a ratio of Si contained in the intergranular regions is higher than a ratio of Si at the center of the soft magnetic particles. 5 . A magnetic core, comprising: the soft magnetic body according to claim 1 . 6 . An electronic component, comprising: the soft magnetic body according to claim 1 .
