<P>PROBLEM TO BE SOLVED: To provide magnetic particles exhibiting ferromagnetism, hard to be flocculated with each other, and applicable without depending on the material of supports, to provide a method of producing the same, and to provide a magnetic recording medium. <P>SOLUTION: The magnetic particles include a ferromagnetic ordered alloy phase, wherein the surface of the magnetic particles is in contact with an organic substance. The method of producing magnetic particles having a ferromagnetic ordered alloy phase includes preparing alloy particles capable of forming the ferromagnetic ordered alloy phase, subjecting the alloy particles to an oxidation treatment, and then annealing the alloy particles in a solvent. The magnetic recording medium includes a magnetic layer which contains the above magnetic particles. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
