Material for anisotropic magnet and method of manufacturing the same

A hot plastically deformed anisotropic magnet having aligned axes of easy magnetization of crystal grains of the magnet, the anisotropic magnet comprising:n(1) a T-based composition consisting of R, B, Ga, and a balance of T and inevitable impurities, wherein R is Pr or Pr that is optionally substituted with at least one element selected from the group consisting of Nd, Dy, and Tb;wherein an amount of R is 12.5 to 15 atomic percent;an amount of B is 4.5 to 6.5 atomic percent; andan amount of Ga is 0.1 to 0.7 atomic percent;wherein T is Fe or Fe partially substituted with Co, and having(2) a degree of magnetic alignment of 0.92 or more, wherein the degree of magnetization is defined by remanence (Br) / saturation magnetization (Js), wherein the remanence (Br) is 1.20 T or more, and a coercivity is 1600 kA/m or more; and(3) flattened crystal grains having a crystal grain diameter of 1 μm or less, and wherein R contains at least 50 atomic percent of Pr.
