Abstract
Disclosed is an R-T-B—Ga-based magnet material ahoy where R is at least one element selected from rare earth metals including Y and excluding Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, 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 RTB phasewhich is a principal phase, and an R-rich phase (and) which is a phase enriched with the R, wherein a non-crystalline phasein the R-rich phase has a Ga content (mass %) that is higher than a Ga content (mass %) of a crystalline phasein 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.
