Energetic selection of ordered states in a model of Er 2 Ti 2 O 7

Abstract

We consider the possibility that the discrete long-range ordered states of Er2Ti2O7 are selected energetically at the mean field level in contrast to an earlier proposal of selection by thermal fluctuations. We show that nearest neighbour exchange interactions alone are not sufficient for this purpose, but that anisotropies arising from excited single ion… (More)
