Soft modes in the easy plane pyrochlore antiferromagnet
J D M Champion, P C W Holdsworth
Thermal fluctuations lift the high ground state degeneracy of the classical nearest neighbour pyrochlore antiferromagnet, with easy plane anisotropy, giving a first order phase tra…
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…
Order in the Heisenberg Pyrochlore: The Magnetic Structure of Gd2Ti2O7
J. D. M. Champion, A. S. Wills, T. Fennell +3
The rare earth pyrochlore material Gd2Ti2O7 is considered to be an ideal model frustrated Heisenberg antiferromagnet with additional dipolar interactions. For this system there are…
