With the object of improving magnetic properties by remaining amorphous phase of a quenched R—Fe—B permanent magnet, in a quenched permanent magnetic material comprising Fe as a major component, at least one lanthanoid element, R, and boron, the permanent magnetic material comprises 10 percent by area or less of a soft magnetic remaining amorphous phase, and the balance being a crystalline phase substantially formed by heat treatment and containing R—Fe—B hard magnetic compound. A bulk magnet is made of the permanent magnetic material by plastic forming.
