Abstract
A soft magnetic core of an inductor or a motor core includes an alloy having a composition of Fe, Si, B, P, Cu, and Y, and the soft magnetic core or the motor core has a composite structure in which crystal grains including Fe are dispersed in an amorphous phase. Also, the alloy is expressed by the compositional formula FeaSibBcPdCueYfCg, wherein a to g satisfy 80≤a≤87, 0≤b≤9, 3≤c≤14, 1≤d≤8, 0.2≤e≤2.5, 0≤f≤3.0, 0≤g≤4.0, and 0≤(e/f)≤4 in terms of atomic percentage value.
