NEW BONDED MAGNET MATERIALS

Recent developments in rare earth intermetallic materials which may be suitable for bonded magnets are reviewed. These include isotropic coe rcive powder with a refined grain structure, isotropic single-phase po wder showing remanence enhancement, exchange-coupled hard/soft nanostr uctures, anisotropic coercive powder, and two-phase dipole-coupled pow ders. Most of these new materials are based on Nd2Fe14B or Sm2Fe17N3. (C) 1997 American Institute of Physics.
