简介 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 RαFe100-α-β-γNβHγ, where R represents at least one element selected from rare earth elements including Y, as well as α, β and γ are atomic percentages satisfying 3≤α≤20, 5≤β≤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.%. COPYRIGHT : (C)2012, JPO&INPIT
