| 简介 |
Disclosed is an R-T-B—Ga-based magnet material alloy where R is at least one element selected from rare earth metals including Y, and T is one or more transition metals with Fe being an essential element. The R-T-B—Ga-based magnet material alloy includes : an R2T14B phase 3 which is a principal phase, and an R-rich phase (1 and 2) which is a phase enriched with the R, wherein a non-crystalline phase 1 in the R-rich phase has a Ga content (mass %) that is higher than a Ga content (mass %) of a crystalline phase 2 in the R-rich phase. With this, it is possible to enhance the magnetic properties of rare earth magnets that are manufactured from the alloy and reduce variations in the magnetic properties thereof. |
