Neutron scattering study of a quasi-2D spin-1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure
Tao Hong, C. Stock, I. Cabrera +5
We report inelastic neutron scattering study of a quasi-two-dimensional S=1/2 dimer system Piperazinium Hexachlorodicuprate under hydrostatic pressure. The spin gap Δ becomes softe…
Spin Order and Excitations in Triangular Antiferromagnet La2Ca2MnO7
Wei Bao, Y. X. Wang, Y. Qiu +6
We report a spin S = 3/2 triangular antiferromagnet with nearest-neighbor coupling J = 0.29 meV in La2Ca2MnO7. A genuinely two-dimensional, three-sublattice order develops below 2.…
Nanoscale freezing of the 2D spin liquid PrGaSiO
H. D. Zhou, C. R. Wiebe, L. Balicas +6
In this letter, we report on the single crystal growth and physical characterization of the distorted kagomé system PrGaSiO. It is found that at zero magnetic field…
Diagonal and Collinear Incommensurate Spin Structures in underdoped LaBaCuO
S. R. Dunsiger, Y. Zhao, B. D. Gaulin +7
We have studied incommensurate spin ordering in single crystal underdoped La_{2-x}Ba_{x}CuO_{4} with x~0.08, 0.05 and 0.025 using neutron scattering techniques. Static incommensura…
Gapped itinerant spin excitations account for missing entropy in the hidden order state of URuSi
C. R. Wiebe, J. A. Janik, G. J. Macdougall +9
One of the primary goals of modern condensed matter physics is to elucidate the nature of the ground state in various electronic systems. Many correlated electron materials, such a…
Field Induced Order and Spin Waves in the Pyrochlore Antiferromagnet Tb2Ti2O7
K. C. Rule, J. P. C. Ruff, B. D. Gaulin +9
High resolution time-of-flight neutron scattering measurements on Tb2Ti2O7 reveal a rich low temperature phase diagram in the presence of a magnetic field applied along [110]. In z…
