R-t-b based rare earth element permanent magnet |
| abstract |
An R-T-B based rare earth element permanent magnet which comprises a sintered product having a main phase comprising an R2T14B phase, where R represents one or more rare elements including Y and T represents one or more transition metal elements comprising Fe or Fe and Co, and a grain boundary phase containing R in a content more than that in the main phase, wherein a product being rich in Zr and having the form of a plate or a needle is present in the R2T14B phase. The R-T-B based rare earth element permanent magnet containing the above allows the suppression of the growth of grains in combination of the minimization of the lowering of magnetic characteristics, and also allows the improvement of the width of sintering temperature. |
