PROBLEM TO BE SOLVED: To provide an anisotropic rare-earth sintered magnet and an anisotropic rare-earth bonded magnet with high Br and high iHc is high a method wherein an R-rich liguid phase is eliminated and the amount of R is reduced as a result. SOLUTION: In an anisotropic rare-earth magnet, its composition is expressed by Ra Feb Coc Bd Ce ADf Mgo [where R represents at least one kind out of rare-earth elements including Nd, Pr, Ce and Dy, AD represents at least one kind out of Al, Zn, Cu, and Ga, M represents at least one kind out of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and W, 22<=a<=38wt.%, (b) represents the remaining part, 12<=c<=70wt.%, 0.4<=d+e<=2wt.%, F<=5wt.% and 0<=g<=10-wt.%]. |
