Abstract:
A soft magnetic alloy has a main component of Fe. The soft magnetic alloy contains P. A Fe-rich phase and a Fe-poor phase are contained. An average concentration of P in the Fe-poor phase is 1.5 times or larger than an average concentration of P in the soft magnetic alloy by number of atoms.
