The Spin Dynamics of the Spin Ladder, Dimer Chain Material Sr14Cu24O41
Roger S Eccleston, Masatomo Uehara, Jun Akimitsu +4
We have performed inelastic neutron scattering on a single crystal sample of Sr14Cu24O41 to study the spin dynamics of the Cu2O3 spin ladder layers, and CuO2 chains. Data collected…

Observation of three-magnon light scattering in CuGeO_3
G. Els, P. H. M. van Loosdrecht, P. Lemmens +7
Temperature and magnetic field dependent polarized Brillouin spectra of CuGeO_3 are reported. In addition to a bound singlet state at 30 cm^{-1}, a new feature has been observed at…

Magnetic ordering, spin waves, and Haldane gap excitations in (Nd_x Y_{1-x})_2 Ba Ni O_5 linear-chain mixed-spin antiferromagnets
T. Yokoo, S. Raymond, A. Zheludev +6
Linear-chain nickelates with the composition (Nd_x Y_{1-x})_2 Ba Ni O_5 (x=1, x=0.75, x=0.5, and x=0.25) are studied in a series of neutron scattering experiments. Powder diffracti…
