Phase transition and thermal order-by-disorder in the pyrochlore antiferromagnet Er sub(2) Ti sub(2) O sub(7): A high-temperature series expansion study

We use a high-temperature series expansion method to study the phenomenon of thermal order-by-disorder in the rare-earth pyrochlore material Er sub(2) Ti sub(2) O sub(7) on its approach to the critical temperature T sub(c). We show that its anisotropic exchange parameters, {J sub(e)}, characterizing...
