Abstract
There are provided a rare-earth permanent magnet, and a method for manufacturing a rare-earth permanent magnet and a system for manufacturing a rare-earth permanent magnet, capable of achieving improved shape uniformity. Magnet material is milled into magnet powder, and the milled magnet powder is formed into a formed body. The formed bodyis calcined and then sintered using a spark plasma sintering apparatus, so that a permanent magnetis manufactured. A die unitincluded in the spark plasma sintering apparatusthat performs spark plasma sintering at least includes in one direction an inflow holeconfigured to receive inflow of part of the pressurized formed body.
