Abstract text

An R-T-B based sintered magnet includes both a light rare-earth element R_L (which is at least one of Nd and Pr) and a heavy rare-earth element R_H (which is at least one of Dy and Tb) and Nd₂Fe₁₄B type crystals as a main phase. The magnet has a first region, which includes either the heavy rare-earth element R_H in a relatively low concentration or no heavy rare-earth elements R_H at all, and a second region, which includes the heavy rare-earth element R_H in a relatively high concentration. The first and second regions are combined together by going through a sintering process.
