Abstract
An amorphous alloy soft magnetic powder has a composition represented by (FeCo)(SiB)M, where M is at least one selected from the group consisting of C, S, P, Sn, Mo, Cu, and Nb, and x, y, a, and b satisfy 0.73≤x≤0.85, 0.02≤y≤0.10, 13.0≤a≤19.0, and 0≤b≤2.0. A Si—K absorption edge XANES spectrum obtained when performing an XAFS measurement on particles has a peak A present in a range of 1842±1 eV, a peak B present in a range of 1845±1 eV, and a peak C present in a range of 1848±1 eV. An intensity ratio A/C is 0.40 or less, and an intensity ratio B/C is 0.60 or less.
