PURPOSE:To obtain a magnet having high residual magnetization, high coercive force and a high energy product by an alloy using Fe as a base by constituting the permanent magnet by one kind of rear-earth elements containing a fixed quantity of Y and a magnetic anisotropic sintered body by a fixed quantity of B and Fe as the remainder. CONSTITUTION:R (where R is at least one kind of the rare-earth elements containing Y) of 8-30% at an atomic percent and the magnetic anisotropic sintered body consisting of 2-28% B and Fe as the remainder are used as magnetic materials for the permanent magnet. The quantities of Fe, B, R of a R compound and B of the magnetic material are optimized, and residual characteristics are obtained by the alloy using Fe as the base. The permanent magnet having high residual characteristics, high coercive force and the high energy product is manufactured easily by the simple alloy. |
