Quantum fluctuations in high field magnetization of 2D square lattice J1-J2 antiferromagnets
P. Thalmeier, M. E. Zhitomirsky, B. Schmidt +1
The J1-J2 square lattice Heisenberg model with spin S=1/2 has three phases with long-range magnetic order and two unconventionally ordered phases depending on the ratio of exchange…

On the Ordering of Na Ions in NaCoO
M. Roger, D. J. P. Morris, D. A. Tennant +8
The influence of electrostatic interactions on the ordering of sodium ions in NaCoO is studied theoretically through Monte-Carlo simulations. For large small di- or tri…

Spin correlations in the paramagnetic phase and ring exchange in lanthanum cuprate
A. M. Toader, J. P. Goff, M. Roger +3
Spin correlations in the paramagnetic phase of lanthanum cuprate have been studied using polarized neutron scattering, with two important results. First, the temperature dependence…
