Inelastic neutron scattering measurements on Nd2Fe14B and Y2Fe14B single crystals
1992
Abstract Inelastic neutron scattering measurements have been carried out on Nd 2 Fe 14 B and Y 2 Fe 14 B single crystals. Temperature dependent acoustic magnon dispersion curves have been found along the high-symmetry directions [0,0,1] and [1,0,0] with a gap at (0,0,2). Soft mode behaviour at spin wave vector q = 0 was observed for Nd 2 Fe 14 B near the spin reorientation temperature. The inelastic scattering intensity decreases steeply for larger q . Therefore, the dispersion curves could be measured until the middle of the Brillouin zone only. The experimental results are discussed in the frame of a classical spin wave model.
Neutron-diffraction study of end-for-end ordering in commensurate submonolayers of carbon monoxide physisorbed on the graphite basal plane
1997
The head-tail (dipolar) ordering in commensurate submonolayer films of carbon monoxide adsorbed on graphite recently observed in heat-capacity measurements for T < 5.18 K has been investigated by neutron diffraction. It will be shown that the experimental results are consistent with an end-for-end ordered commensurate herringbone structure.
