摘要
An FeNi ordered alloy has an L10 ordered structure, a mean order degree of 0.4 or more throughout a material, and a coercivity of 87.5 kA/m or more. For example, a nitriding treatment of an FeNi random alloy is performed and then a nitriding treatment is performed to obtain an L10-FeNi ordered alloy. A volume mean particle size of a FeNi random alloy is, for example, 45 nm or more, and a treatment temperature of the nitriding treatment is, for example, greater than or equal to 300 degrees Celsius and is less than or equal to 500 degrees Celsius, and a treatment period is, for example, 10 hours or longer.
