Abstract
A soft magnetic metal powder is manufactured. An aqueous solution of at least one of aluminum, silicon, a rare-earth element (including Y), and magnesium is added into a solution containing an iron ion while blowing a gas containing oxygen thereinto, to form a precursor containing at least one of aluminum, silicon, a rare-earth element (including Y), and magnesium. The precursor is reduced to obtain a metal powder. The metal powder is further slowly oxidized with oxygen to form an oxidized film on the surface of the metal powder.
