Abstract:
Provided are a soft magnetic alloy powder, a compact made from the soft magnetic alloy powder, a powder magnetic core including the compact, and a magnetic element including the powder magnetic core. The soft magnetic alloy powder contains Fe—Ni-based particles containing 38% to 48% by mass Ni, 1.0% to 15% by mass Co, and 1.2% to 10% by mass Si relative to the total mass of Fe, Ni, Co, and Si, the remainder being Fe. The Fe—Ni-based particles have an average size of more than 1 μm to less than 10 μm.
