Abstract

The pyrochlore material Ho₂Ti₂ O₇ exhibits spin ice correlations at low temperature. Diffuse magnetic neutron scattering is quite well described by a nearest neighbor spin ice model and very accurately described by a dipolar spin ice model. The heat capacity is well accounted for by the sum of a dipolar spin ice contribution and an expected nuclear spin contribution, known to exist in other Ho³⁺ salts. These results settle the question of the nature of the low temperature spin correlations in Ho₂Ti₂ O₇ for which contradictory claims have been made.
