Abstract
A magnetic material includes an FeNi ordered alloy. The FeNi ordered alloy has L1ordered structure and is provided as an acicular particle having a longer axis and a shorter axis. A method for manufacturing a magnetic material including an FeNi ordered alloy includes preparing an FeNi disordered alloy provided as an acicular particle, and performing a nitriding treatment of nitriding the FeNi disordered alloy. The magnetic material manufacturing method further includes obtaining an L1-type FeNi ordered alloy provided as the acicular particle, by performing a denitrification treatment of removing nitrogen from the FeNi disordered alloy on which the nitriding treatment has been performed.
