Antiferromagnetic vortex state in a high-temperature superconductor
B. Lake, H. M. Ronnow, N. B. Christensen +10
There is strong evidence that magnetic interactions play a crucial role in the mechanism driving high-temperature superconductivity in cuprate superconductors. To investigate this…
The Spallation Neutron Source: A Powerful Tool for Materials Research
T. E. Mason, T. A. Gabriel, R. K. Crawford +3
The wavelengths and energies of thermal and cold neutrons are ideally matched to the length and energy scales in the materials that underpin technologies of the present and future:…
Neutron Scattering Studies of Spin Fluctuations in High Temperature Superconductors
T. E. Mason
Neutron scattering can provide detailed information about the energy and momentum dependence of the magnetic dynamics of materials provided sufficiently large single crystals are a…
New Far Infrared Vibrational Mode in Zn Doped CuGeO3
J. J. McGuire, T. Room, T. E. Mason +4
We report on far infrared measurements on Zn and Si doped crystals of the spin-Peierls compound CuGeO3. Zn doping has the effect of introducing several new absorption lines, polari…
Neutron Scattering Studies of Heavy Fermion Systems
T. E. Mason, G. Aeppli
We review the results of recent studies of the elastic and inelastic neutron scattering from a variety of heavy fermion compounds. This class of materials exhibits a rich variety o…
Magnetic correlations in deuteronium jarosite, a model S=5/2 Kagome antiferromagnet
A. S. Wills, A Harrison, S. A. M. Mentink +2
Deuteronium jarosite, (D_3O)Fe_3(SO_4)_2(OD)_6, contains a kagome lattice of Heisenberg spins, S=5/2, with a coverage of 97+-1%. DC and AC susceptibility measurements show strong i…
