Er2Ti2O7: Evidence of Order by Disorder in a Frustrated Antiferromagnet
J. D. M. Champion, M. J. Harris, P. C. W. Holdsworth +14
Er_2Ti_2O_7 has been suggested to be a realization of the frustrated < 111 > XY pyrochlore lattice antiferromagnet, for which theory predicts fluctuation-induced symmetry breaking…

Field Induced Partial Order in the Spin-Ice Dysprosium Titanate
T. Fennell, O. A. Petrenko, G. Balakrishnan +5
Neutron scattering has been used to investigate the magnetic correlations in the the spin ice material dysprosium titanate, Dy2Ti2O7. An isotopically enriched sample was used to mi…

Spin Correlations in HoTiO: a Dipolar Spin Ice System
S. T. Bramwell, M. J. Harris, B. C. den Hertog +8
The pyrochlore material has been suggested to show ``spin ice'' behaviour. We present neutron scattering and specific heat results that establish unambiguou…
