A process for producing a rare earth magnet of magnetically improved performance wherein a specific titanate coupling agent is added in one step of the process to enhance the oxidation resistance of the raw materials during production and a special degassing step is incorporated to allow for the removal of the residual titanate coupling agent. The resultant rare earth magnet exhibits improved maximum magnetic energy product ((BH).sub.max) and magnetic coercive force (H.sub.c) as well as other magnetic properties. Rare earth magnet produced by the process is also disclosed.
