Permanent magnet alloy

Abstract

Abstract PURPOSE:To obtain a permanent magnet alloy having improved coercive force and stabilized high magnetic characteristics by blending Pr, Fe, B, Zn, etc. in a ratio represented by a specified formula. CONSTITUTION:A permanent magnet alloy having a composition represented by a formula R(T1-x-yMxM'y)z (where R is one or more among Pr, Ce, Sm and Nd, T is Fe or Fe and Co, M is B or two or more among B, Si, C and P, M' is one or more among Zn, Ga and In, 0.02<=x<=0.15, 0.005<=y<=0.1, and 4<=z<=8.5) is manufactured by melting, casting, grinding, compression in the presence or absence of a magnetic field, sintering and soln.heat treatment.
