Abstract

Alloy powder of a composition formula FeCoBSiPCuChaving an amorphous phase as a main phase is provided. Parameters satisfy the following conditions: 3.5≤a≤4.5 at %, 6≤b≤15 at %, 2≤c≤11 at %, 3≤d≤5 at %, 0.5≤e≤1.1 at %, and 0≤f≤2 at %. With this composition, the alloy powder has good magnetic characteristics even when it has a large particle diameter such as 90 μm. Therefore, yield thereof is improved.
