High-energy spin waves in the spin-1 square-lattice antiferromagnet LaNiO
A. N. Petsch, N. S. Headings, D. Prabhakaran +5
Inelastic neutron scattering is used to study the magnetic excitations of the square-lattice antiferromagnet LaNiO. We find that the spin waves cannot be described by…
Scaling of dynamic spin correlations in BaCu2SiGeO7
A. Zheludev, T. Masuda, G. Dhalenne +3
The magnetic dynamic structure factor of the one-dimensional S = 1/2 chain system BaCu2(Si0.5Ge0.5)2O7 is studied in a wide range of energy transfers and temperatures. Contrary to…
Localized excitation in the hybridization gap in YbAl3
A. D. Christianson, J. M. Lawrence, E. A. Goremychkin +6
The intermediate valence compound YbAl3 exhibits a broad magnetic excitation with characteristic energy E1 ~ 50meV, of order of the Kondo energy (TK ~ 600-700K). In the low tempera…
Anisotropy in the electronic screening of oxygen lattice modes in YBa(2)Cu(3)O(6.95)
R. J. McQueeney, T. Egami, J. -H. Chung +7
Inelastic neutron scattering data from a twinned single-crystal of YBa2Cu3O6.95 are presented that show a distinct a-b plane anisotropy in the oxygen vibrations. The Cu-O bond-stre…
