Abstract
A method for manufacturing FeNi ordered alloy having a L10 type order structure is provided. After a nitrification process for nitriding a powder sample (100) of a FeNi disordered alloy arranged in a tube furnace (10) is performed using a NH3 gas, a de-nitrification process for removing a nitrogen from the FeNi disordered alloy which is processed by the nitrification process is performed using a H2 gas. Thus, the L10 type FeNi ordered alloy with a regularity defined by S equal to or higher than 0.5 is obtained.
