Abstract:

Hexagonal intermetallic compounds close to R2M17 stoichiometry in the Lu-Fe, Th-Ni, Y-Ni, and Er-Co systems have been studied by single crystal x-ray techniques. Additional neutron diffraction studies were made of the Lu-Fe compound. The thermal variation of lattice parameters of rare earth-transition metal intermetallic compounds rich in Fe, Co, or Ni in the temperature range 25-900K was studied. Lattice parameter measurements have been made on YxLa1-x FeyCo5-y alloys. Neutron diffraction studies of LuFe9.5 and HoFe3 were made to determine their magnetic structure. The ferromagnetic behavior of LuFe9.5 up to 100K has been confirmed. Author
