PROBLEM TO BE SOLVED: To provide an Fe based soft magnetic alloy having low core loss in addition to high saturation magnetic flux density and particularly excellent soft magnetic properties. SOLUTION: In the nanocrystal soft magnetic alloy obtained by subjecting a rapidly cooled thin strip alloy produced by a melt quenching method to heat treatment, and consisting of a fine bcc phase of Fe having a grain size of <=100 nm as the main phase, an element Q having the positive value of a mixed enthalpy ΔH with Fe is contained by >=0.01 atomic % as an essential component. |
