Abstract: A method of making a rare earth magnet containing zero heavy rare earth elements includes a step of mixing the fine grain powder with the lubricant having a weight content of at least 0.03 wt. % and no greater than 0.2 wt. % for a period of between 1 and 2 hours. The step of pulverizing is further defined as jet milling the alloy powder with the lubricant using a carrier gas of argon or nitrogen. The method further includes a step of controlling oxygen content during the steps of melting, forming, disintegrating, mixing, pulverizing, molding, and sintering whereby the impurities including Carbon (C), Oxygen (O), and Nitrogen (N) satisfies 1.2C+0.6O+N?2800 ppm. A rare earth magnet composition including C, O, and N whereby C, O, and N satisfies 1.2C+0.6O+N?2800 ppm and has zero heavy rare earth elements.
