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…

Quantum phase transitions in magnetism and superconductivity: emergent spin topology seen with neutrons
W. J. L. Buyers, C. Stock, Z. Yamani +7
Magnetic spins and charges interact strongly in high-temperature superconductors. New physics emerges as layers of copper oxide are tuned towards the boundary of the superconductin…

From incommensurate to dispersive spin-fluctuations: The high-energy inelastic spectrum in superconducting YBa2Cu3O6.5
C. Stock, W. J. L. Buyers, R. A. Cowley +8
We have investigated the spin fluctuations at energy transfers up to ~110 meV, well above the resonance energy (33 meV) in the YBa2Cu3O6.5 ortho-II superconductor using neutron tim…
