PROBLEM TO BE SOLVED: To provide soft magnetic alloy powder which includes Fe-Ni-based crystal particles and is low in the loss in a high-frequency region, high in magnetic permeability, and excellent in productivity and economic efficiency.SOLUTION: The soft magnetic alloy powder comprises Fe-Ni-based particles including, to the total mass of iron, nickel, cobalt and silicon, 38-48 mass% of the nickel, 1.0-15 mass% of the cobalt, and 1.2-10 mass% of the silicon with the balance consisting of the iron. It is desired that the Fe-Ni-based particles have an average particle diameter of 1-10 μm. The powder-compact magnetic core comprises a powder compact made of the soft magnetic alloy powder. The magnetic device includes the powder-compact magnetic core. |
