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 Y(x)La(1-x) Fe(y)Co(5-y) alloys. Neutron diffraction studies of LuFe(9.5) and HoFe3 were made to determine their magnetic structure. The ferromagnetic behavior of LuFe(9.5) up to 100K has been confirmed. (Author)
