An FeNi ordered alloy contained in a magnetic material has an L1ordered structure, is doped with an light element, and is provided as a granular particle. A method for manufacturing a magnetic material including an FeNi ordered alloy having an L1ordered structure includes preparing an FeNi ordered alloy provided as a granular particle, and doping a light element into the FeNi ordered alloy.

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.

An L10-FeNi magnetic powder has an average particle size of 50 nm to 1 &#x3bc;m, and an average value of sphericity P of 0.9 or more. The sphericity P is defined as P=Ls/Lr, where Lr is a perimeter of an L10-FeNi magnetic powder particle on an image of a microscope, and Ls is a perimeter of a perfect circle that has a same area as the L10-FeNi magnetic powder particle on the image for which Lr is calculated.
