Neutron scattering measurements of and spin-orbit excitations below the Mott-Hubbard gap in CoO
R. A. Cowley, W. J. L. Buyers, C. Stock +4
Neutron scattering is used to investigate the single-ion spin and orbital excitations below the Mott-Hubbard gap in CoO. Three excitations are reported at 0.870 0.009 eV, 1.8…
The effect of the pseudogap on suppressing high energy inelastic neutron scattering in superconducting YBa2Cu3O6.5
C. Stock, R. A. Cowley, W. J. L. Buyers +6
We have measured the spin fluctuations in the YBa2Cu3O6.5 (YBCO6.5, Tc=59 K) superconductor at high-energy transfers above ~ 100 meV. Within experimental error, the momentum depend…
Direct observation of paramagnons in palladium
R. Doubble, S. M. Hayden, Pengcheng Dai +3
We report an inelastic neutron scattering study of the spin fluctuations in the nearly-ferromagnetic element palladium. Dispersive over-damped collective magnetic excitations or ``…
The emergence of coherent magnetic excitations in the pseudogap phase of La2-xSrxCuO4
O. J. Lipscombe, B. Vignolle, T. G. Perring +2
We use inelastic neutron scattering to measure the magnetic excitations in the underdoped superconductor La2-xSrxCuO4 (x=0.085, Tc=22 K) over energy and temperatures ranges 5 < E <…
Evidence for decay of spin-waves above the pseudogap in underdoped YBa2Cu3O6.35
C. Stock, R. A. Cowley, W. J. L. Buyers +7
The magnetic spectrum at high-energies in heavily underdoped YBaCuO (T=18 K) has been determined throughout the Brillouin zone. At low-energy the scatter…
Two energy scales in the spin excitations of the high-T_c superconductor LaSrCuO
B. Vignolle, S. M. Hayden, D. F. McMorrow +4
The excitations responsible for producing high-temperature superconductivity in the cuprates have not been identified. Two promising candidates are collective spin excitations and…
