Spinons in the strongly correlated copper oxide chains in SrCuO2
I. A. Zaliznyak, H. Woo, T. G. Perring +3
We have investigated the spin dynamics in the strongly correlated chain copper oxide SrCuO for energies up to eV using inelastic neutron scattering. We observe an…
Ferromagnetic in-plane spin fluctuations in NaxCoO2 observed by neutron inelastic scattering
A. T. Boothroyd, R. Coldea, D. A. Tennant +3
We present neutron scattering spectra taken from a single crystal of Na0.75CoO2, the precursor to a novel cobalt-oxide superconductor. The data contain a prominent inelastic signal…
Spin excitations in stripe-ordered La2-xSrxNiO4 (x=0.275 and 1/3)
A. T. Boothroyd, P. G. Freeman, D. Prabhakaran +5
We report neutron scattering measurements of the spectrum of magnetic excitations in the stripe-ordered phase of La2-xSrxNiO4 (x=0.275 and 1/3). The propagating spin excitations fo…
Temperature-induced barium de-trapping from a double-well potential in Ba6Ge25
M. Schmidt, P. G. Radaelli, M. J. Gutmann +3
The crystal structure of barium-germanium clathrate Ba6Ge25 was studied using neutron powder diffraction in the temperature range 20-300K. The compound was found to be cubic (S.G.…
