Title:
SOFT MAGNETIC MATERIAL COMPOSITION, METHOD FOR MANUFACTURING THE SAME, MAGNETIC CORE, AND COIL TYPE ELECTRONIC COMPONENT
Document Type and Number:
Japanese Patent JP2015028985
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a soft magnetic material composition superior in strength, a method for manufacturing such a soft magnetic material composition, a magnetic core, and a coil type electronic component.SOLUTION: A soft magnetic material composition comprises: soft magnetic alloy particles; and grain boundaries present between the soft magnetic alloy particles. The soft magnetic alloy particles are made of an Fe-Si-M based soft magnetic alloy or Fe-Ni-Si-M based soft magnetic alloy (where M represents at least one element selected from a group consisting of Cr, Al, Ti, Co and Ni). At the grain boundaries, Zn-containing glass-like phases are present.
