<div notation="docdba" type="abstract" xml:base="/api/emi/section/fea1a42c-3bc7-45ff-83cb-7af0aacbf9b3/image" xml:lang="en"><p>A soft magnetic alloy includes a composition of (Fe&lt;sub>(1-(α+β))&lt;/sub>X1&lt;sub>α&lt;/sub>X2&lt;sub>β&lt;/sub>)&lt;sub>(1-(a+b+c+d+e+f+g))&lt;/sub>M&lt;sub>a&lt;/sub>Ti&lt;sub>b&lt;/sub>B&lt;sub>c&lt;/sub>P&lt;sub>d&lt;/sub>Si&lt;sub>e&lt;/sub>S&lt;sub>f&lt;/sub>C&lt;sub>g&lt;/sub>. X1 is one or more of Co and Ni. X2 is one or more of Al, Mn, Ag, Zn, Sn, As, Sb, Cu, Cr, Bi, N, O, and rare earth elements. M is one or more of Nb, Hf, Zr, Ta, Mo, W, and V. 0.020≤ a+b ≤0.140, 0.001≤ b ≤0.140, 0.020&lt; c ≤0.200, 0.010≤ d ≤0.150, 0≤ e ≤0.060, a ≥0, f ≥0, g ≥0, a+b+c+d+e+f+g &lt;1, α≥0, β≥0, and 0≤α+β≤0.50 are satisfied. The soft magnetic alloy has a nanohetero structure or a structure of Fe-based nanocrystalline.</p></div>
