Soft magnetic alloy and magnetic device

Abstract

A soft magnetic alloy including a composition having a formula of ((Fe(1−(α+β))X1αX2β)(1−(a+b+d+e))MaBbCrdCue)1−fCf. X1 is one or more elements selected from a group of Co and Ni. X2 is one or more elements selected from a group of W, Al, Mn, Ag, Zn, Sn, As, Sb, Bi, N, O, and rare earth elements. M is one or more elements selected from a group of Nb, Hf, Zr, Ta, Ti, Mo, and V. 0.030≤a≤0.14, 0.028≤b≤0.15, 0.005≤d≤0.020, 0<e≤0.030, 0≤f≤0.040, α≥0, β≥0, and 0≤α+β≤0.50 are satisfied.
