Resumen
The magnetic properties of Ho 2Sn 2O 7have been investigated and compared to other spin ice compounds. Although the lattice has expanded by 3% relative to the better studied Ho 2Ti 2O 7spin ice, no significant changes were observed in the high temperature properties, T20K. As the temperature is lowered and correlations develop, Ho 2Sn 2O 7enters its quantum phase at a slightly higher temperature than Ho 2Ti 2O 7and is more antiferromagnetic in character. Below 80K a weak inelastic mode associated with the holmium nuclear spin system has been measured. The hyperfine field at the holmium nucleus was found to be 700T. © 2012 IOP Publishing Ltd. 24 7
