Magnetic material

Abstract

Disclosed is a magnetic material which suppresses formation of impurity phase of Fe, Co or Fe-Co alloy, possesses a stable ThMn.sub.12 crystal structure as the principal phase, and is excellent in magnetic properties and lower in cost. Such magnetic material is expressed in a general formula: R1.sub.x R2.sub.y Si.sub.z M.sub.u T.sub.v where R1is at least one element selected from Zr and Hf, R2is at least one element selected from rare earth element, M is at least one element selected from C, N and P, T is at least one element selected from Fe and Co, x+y+z+u+v=100, x, y, z, u, v are atomic percent individually defined as 0.1.ltoreq.x.ltoreq.20, 2.ltoreq.y.ltoreq.20, 0.5.ltoreq.z.ltoreq.20, 0.ltoreq.u.ltoreq.20, v.gtoreq.50, and of which principal phase possesses a ThMn.sub.12 crystal structure.
