Cascade of field-induced magnetic transitions in a frustrated antiferromagnetic metal
A. I. Coldea, L. Seabra, A. McCollam +10
Frustrated magnets can exhibit many novel forms of order when exposed to high magnetic fields, however, much less is known about materials where frustration occurs in the presence…
Interplay between superconductivity and ferromagnetism in epitaxial Nb(110)/Au(111)/Co(0001) trilayers
Hiroki Yamazaki, Nic Shannon, Hidenori Takagi
Epitaxially grown multilayer systems offer the possibility to study the influence of ferromagnetism on superconductivity in a new and controlled way. In this paper, we explore how…
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…
Mixed valence on a pyrochlore lattice - LiV2O4 as a geometrically frustrated magnet
Nic Shannon
Above 40K, the magnetic susceptibility of the heavy Fermion spinel LiV2O4 has many features in common with those of geometrically frustrated magnetic insulators, while its room tem…
