Abstract
Provided is a soft magnetic alloy including a Fe-based nanocrystal and metallic glass. A differential scanning calorimetry curve of the soft magnetic alloy has a glass transition point Tg, a temperature rising rate of the soft magnetic alloy in measurement of the differential scanning calorimetry curve is 40 K/minute, and a temperature Tp of a maximum exothermic peak in the differential scanning calorimetry curve is higher than the Tg.
