SOFT MAGNETIC ALLOY POWDER, MAGNETIC CORE, MAGNETISM APPLICATION COMPONENT, AND NOISE SUPPRESSION SHEET

Document Type and Number:

WIPO Patent Application WO/2021/200600

Kind Code:

A1

Abstract:

Provided is a soft magnetic alloy powder 1 which contains soft magnetic alloy particles 10 having an amorphous phase. The soft magnetic alloy particles 10 have a chemical composition represented by FeaSibBcCdPeCufSngM1hM2i, wherein: M1 is one or more types of chemical elements from among Co and Ni; M2 is one or more types of chemical elements from among Ti, Zr, Hf, Nb, Ta, Mo, W, Cr, Al, Mn, Ag, V, Zn, As, Sb, Bi, Y, and rare earth elements; and the equations 79≤a＋h＋i≤86, 0≤b≤5, 7.2≤c≤12.2, 0.1≤d≤3, 7.3≤c＋d≤13.2, 0.5≤e≤10, 0.4≤f≤2, 0.3≤g≤6, 0≤h≤30, 0≤i≤5, and a＋b＋c＋d＋e＋f＋g＋h＋i=100 (parts by mole) are satisfied. The average ratio of minor axis length Y to major axis length X of a two-dimensional projection shape of the soft magnetic alloy particles 10 is 0.69-1, inclusive.
