1. A magnetic material comprising an FeNi ordered alloy,
the FeNi ordered alloy having an L10 ordered structure, doped with at least one or more of: B, C, and N, as a light element, and provided as a granular particle, wherein the FeNi ordered alloy having the L10 ordered structure is an L10-FeNi ordered alloy, and
wherein
the granular particle doped with the light element is provided as at least one of:
a granular particle that has a main phase not doped with the light element at a center portion of the granular particle constituting the FeNi ordered alloy and that has a doped phase incorporated with the light element at a surface layer surrounding the center portion; and
a granular particle that has a doped phase incorporated with the light element at a center portion of the granular particle constituting the FeNi ordered alloy and that has a main phase not doped with the light element at a surface layer surrounding the center portion.
