Abstract: An L10 type iron-nickel (FeNi) ordered alloy has an L10 type ordered structure and contains sulfur. The L10 type FeNi ordered alloy may have a sulfur content in a range from 0.01% by mass to 10% by mass. A manufacturing method of an L10 type FeNi ordered alloy includes performing a nitriding treatment to an FeNi alloy containing sulfur to obtain a nitride containing Fe and Ni.
