Neutron di⁄raction study of Nd 5 Fe 17

Nd 5 Fe 17 is a new stable phase in the binary Nd—Fe system. X-ray di⁄raction of single crystals revealed a complex structure belonging to the hexagonal space group P6 3 /mcm. We perform a neutron di⁄raction study of Nd 5 Fe 17 powders. Position parameters, occupation of atoms, magnetic moment, coordination number, and average bond length in the hexagonal structure are reported. ( 1998 Elsevier Science B.V. All rights reserved.
