SOFT MAGNETIC ALLOY, SOFT MAGNETIC ALLOY RIBBON, METHOD OF MANUFACTURING SOFT MAGNETIC ALLOY RIBBON, MAGNETIC CORE, AND COMPONENT

摘要

The soft magnetic alloy of the present disclosure is represented by a composition formula of Fe_aSi_bB_cCu_dM_e where M is at least one type of element selected from a group consisting of Nb, Mo, V, Zr, Hf, and W, and the formula satisfies 82.5≤a≤86, 0.3≤b≤3, 12.5≤c≤15.0, 0.05≤d≤0.9, and 0≤e<0.4 in at %. The soft magnetic alloy includes a structure that has a crystal grain with a grain diameter of 60 nm or less in an amorphous phase.
