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 insulating...
Stock, C., Buyers, W. J. L., Yamani, Z., Broholm, C., Tun, Z., ...
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. No coexistence with...
Stock, C., Buyers, W. J. L., Liang, R., Peets, D., Tun, Z., Bonn, D., ...
We describe the relation between spin fluctuations and superconductivity in a highly-ordered sample of YBaCu3O6.5 using both polarized and unpolarized neutron inelastic scattering. The spin...
Top-Seeded Melt-Growth of YBa_2Cu_3O_x Crystals for Neutron Diffraction Studies (2002)
Peets, D. C., Liang, Ruixing, Stock, C., Buyers, W. J. L., Tun, Z., Taillefer, L., ...
We have grown cubic centimetre-size crystals of YBa2Cu3Ox suitable for neutron studies, by a top-seeded melt-growth technique. Growth conditions were optimized with an eye toward maximizing phase...
Neutron scattering search for static magnetism in oxygen ordered YBa2Cu3O6.5 (2002)
Stock, C., Buyers, W. J. L., Tun, Z., Liang, R., Peets, D., Bonn, D., ...
We present elastic and inelastic neutron scattering results on highly oxygen ordered YBa2Cu3O6.5 ortho-II. We find no evidence for the presence of ordered magnetic moments to a sensitivity of 0.003...
Kenzelmann, M., Cowley, R. A., Buyers, W. J. L., Tun, Z., Coldea, R., Enderle, M.
We report inelastic time-of-flight and triple-axis neutron scattering measurements of the excitation spectrum of the coupled antiferromagnetic spin-1 Heisenberg chain system CsNiCl3. Measurements...
Field dependence of the incommensurate magnetic order in UNiGe (2001)
Nakotte, H., Chang, S., Tun, Z., Prokes, K., Svoboda, P., Sechovsky, V., ...
Between 42 and 50 K, UNiGe exhibits an incommensurate phase (IP) with q (=0, , ) with a that is slightly larger than in zero "eld. We have studied the "eld dependence of this magnetic structure by...

SYMMETRY OF SPIN WAVES AND HALDANE GAP IN CsNiCl3 (1988)
Tun, Z., Buyers, W., Armstrong, R., Hallman, E., Arovas, D.
Neutron scattering experiments and theoretical calculations on CsNiCl3 show that linear theory fails for the spin wave polarization in the 3-D phase. In the 1-D phase the Haldane mode is observed to...
