PROBLEM TO BE SOLVED: To provide a solid material which is used for a solid magnet, has superior magnetic characteristic, is high in density, thermal stability, and oxidation resistance, and solidified by metallic bond. SOLUTION: Material powder consisting rare earth-iron-nitrogen-hydrogen magnetic material that a rhombohedral or a hexagonal crystal structure is formed into a molded body by compaction, and the molded body is shock- compressed and solidified into the solid material for magnet by the use of underwater shock waves. |
