Spin dynamics near the critical doping in weakly-superconducting underdoped YBa2Cu3O6.35 (Tc=18K)
C. Stock, W. J. L. Buyers, Z. Yamani +5
Using neutron scattering we have determined the magnetic structure and fluctuations in the YBa2Cu3O6.35 superconductor (Tc=18 K). The long-range ordered collinear spins of the insu…
Orbital and Spin Excitations in Cobalt Oxide
Z. Yamani, W. J. L. Buyers, R. A. Cowley +1
By means of neutron scattering we have determined new branches of magnetic excitations in orbitally active CoO (TN=290 K) up to 15 THz and for temperatures from 6 K to 450 K. Data…
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…
Central mode and spin confinement near the boundary of the superconducting phase in YBa2Cu3O6.353 (Tc=18 K)
C. Stock, W. J. L. Buyers, Z. Yamani +8
We have mapped the neutron scattering spin spectrum at low-energies in YBa2Cu3O6.353 (Tc=18 K) where the doping ~0.06 is near the critical value (pc=0.055) for superconductivity. N…
