PROBLEM TO BE SOLVED: To produce a rare earth-iron-nitrogen magnetic alloy capable of nitriding treatment in a time shorter than heretofore and improved in productivity. SOLUTION: This magnetic alloy is an alloy, containing rare earth elements (one or >=2 kinds among lanthanoide series elements including Y), iron, and nitrogen as essential constituents and also containing 0.001-0.1wt.% of at least one or more elements among Li, Na, K, Rb, Cs, Mg, Ca, Sr, and Ba, or is an alloy containing rare earth elements, iron, nitrogen, and M (where M is at least one or more elements among Ti, V, Cr, Mn, Cu, Zr, Nb, Mo, Hf, Ta, W, Al, Si, and C) as essential constituents and also containing 0.001-0.1wt.% of at least one or more elements among Li, Na, K, Rb, Cs, Mg, Ca, Sr, and Ba. |
