Universal magnetic excitation spectrum in cuprates (2004)
Tranquada, J. M., Woo, H., Perring, T. G., Goka, H., Gu, G. D., Xu, G., ...
We have recently used inelastic neutron scattering to measure the magnetic excitation spectrum of La(1.875)Ba(0.125)CuO(4) up to 200 meV. This particular cuprate is of interest because it exhibits...
Quantum Magnetic Excitations from Stripes in Copper-Oxide Superconductors (2004)
Tranquada, J. M., Woo, H., Perring, T. G., Goka, H., Gu, G. D., Xu, G., ...
In the copper-oxide parent compounds of the high-transition-temperature superconductors, the valence electrons are localized, one per copper site, due to strong intraatomic Coulomb repulsion. A...

We have investigated the spin dynamics in the strongly correlated chain copper oxide SrCuO$_2$ for energies up to $\gtrsim 0.6$ eV using inelastic neutron scattering. We observe an acoustic band of...
Spin excitations in stripe-ordered La2-xSrxNiO4 (x=0.275 and 1/3) (2003)
Boothroyd, A. T., Freeman, P. G., Prabhakaran, D., Woo, H., Nakajima, K., Tranquada, J. M., ...
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 follow a similar...
