A compound for a rare-earth bonded magnet includes a rare-earth alloy powder and a binder. The rare-earth alloy powder includes at least 2 mass % of Ti-containing nanocomposite magnet powder particles with a composition represented by (Fe1-mTm)100-x-y-zQxRyMz, where T is Co and/or Ni; Q is B with or without C; R is at least one rare-earth element substantially excluding La and Ce; M is at least one metal element selected from Ti, Zr and Hf and always includes Ti; and 10<x</=20 at%; 6</=y<10 at%; 0.1</=z</=12 at%; and 0</=m</= 0.5. The particles include at least two ferromagnetic crystalline phases, in which hard magnetic phases have an average crystal grain size of 10 nm to 200 nm, soft magnetic phases have an average crystal grain size of 1 nm to 100 nm, and the average crystal grain size of the soft magnetic phases is smaller than that of the hard magnetic phases. <IMAGE> |
