Abstract
An FeNi ordered alloy contained in a magnetic material has an L10 ordered 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 L10 ordered structure includes preparing an FeNi ordered alloy provided as a granular particle, and doping a light element into the FeNi ordered alloy.
Claims9
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.
