  • Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7 

    Ruff, J. P. C., J. P. Clancy, A. Bourque, M. A. White, et al. 2008. "Spin waves and quantum criticality in the frustrated XY pyrochlore antiferromagnet Er2Ti2O7." Physical Review Letters 101(14): 147205-147205. Copyright © 2008 American Physical Society.
    We report detailed measurements of the low temperature magnetic phase diagram of Er2Ti2O7. Heat capacity and time- of- flight neutron scattering studies of single crystals reveal unconventional low- energy states. Er3+ ...
