Magnetic structure of Nd7Ni3 (original) (raw)

The magnetic structure of a hexagonal intermetallic compound Nd 7 Ni 3 has been studied by the neutron diffraction measurements. The Rietveld analysis was carried out to refine the structural and magnetic parameters. The refined propagation vector is Q = (0 0 0.32(2)) to describe the ferrimagnetic structure at 2.0 K. The magnetic moment of the Nd atom is 2.00(1), 2.09(1), 2.09(1) B for the sites I, II and III, respectively. The magnetic moment at the site I has the conical structure with the cone angle 22.00(1) • . The refined initial relative phase is 39.43(3) • for sites I and II and 41.43(5) • for sites II and III, respectively.
