FIELD: powder metallurgy; magnetic materials for permanent magnets using rare-earth elements with iron group of metals. SUBSTANCE: magnetic material has in its composition iron, cobalt, boron, neodymium, and also at least one rare-earth element chosen from following group: terbium, dysprosium, holmium, erbium, thulium, and at least one rare-earth element chosen of following group: samarium, lanthanum, cerium, praseodymium, chemical composition being in compliance with following formula, atom percent: (Nd1-x 1-x2R1x1R2x2)14-20(Fe1-y1Coy1)resB5-8, where R1 is at least one element chosen from Tb, Dy, Ho, Er, Tm, and R2 group, at least one element chosen from Sm, La, Ce, Pr, x1 + x2 = 0.05-0.99. x2/x1 = 0.01-9, y1 = 0.05-0.35 group. Magnetic material has in addition at least one element chosen from following group: aluminum, gallium, titanium, niobium, molybdenum, copper, its chemical composition being in compliance with following formula, atom percent: (Nd1-x 1-x2R1x1R2x2)14-20(Fe1-y1Coy1)resB4-9, where T is at least one element chosen from Al, Ga, Ti, Nb, Mo, y2 = 0.01-5, Cu group. Part made of proposed material is described. EFFECT: enhanced magnetic properties and strength of parts, increased yield of radial-structure annular magnets. 3 cl, 1 tbl
