A method of fabricating a rare-earth based sintered magnet having improved magnetic and mechanical characteristics is offered. Also, a method of fabricating a rare-earth bonded magnet having improved magnetic and mechanical characteristics is offered. The method of fabricating the rare-earth based sintered magnet is started with preparing powder of an alloy including a rare-earth element and a transition metal. The powder of the alloy is mixed with an additive. The mixture is compression molded and irradiated with microwaves to cause the powder to self-heat. As a result, the mixture is sintered.
