Abstract:
Provided herein is a soft magnetic alloy powder that can exhibit a high saturation flux density and desirable soft magnetic characteristics. A dust core using the soft magnetic alloy powder is also provided. The soft magnetic alloy powder is an Fe-based nanocrystalline soft magnetic alloy powder of a crystallized Fe-based amorphous soft magnetic alloy powder, and has a DSC curve with a first peak that is 15% or less of a first peak of the Fe-based amorphous soft magnetic alloy in terms of a maximum value.
