Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid material for magnets which is solidified by metallic bonds and has high density, high magnetic performance, excellent thermal stability and excellent oxidation resistance.SOLUTION: A rare earth-iron-nitrogen-hydrogen-based magnetic material with a rhombohedral or hexagonal crystal structure is represented by general formula RFeNH, where R represents at least one element selected from rare earth elements including Y, as well as α, and γ are atomic percentages satisfying 3≤α≤20, 5≤ ≤30, and 0.01≤γ≤10. The content of the rare earth-iron-nitrogen-hydrogen-based magnetic material in the solid material for magnets is 80-100 vol.%.
