Abstract
The invention describes a sintered rare earth magnet with a concentration of c of 8001,400 ppm, a maximum concentration of o of 1,000 ppm, and a maximum concentration of N of 800 ppm, a maximum average crystal grain size D50 of 4.5 ppm, and an orientation Or (%) determined by the formula: Or ” (Br / 47tfs)*100, in which D50 and Or satisfy the relationship: Or > 0f7*D5O+95. The sintered magnet shows both high values of Br and HCJ.
