|Title:||Low energy spin dynamics in the spin ice Ho2Sn2O7|
|Abstract:||The magnetic properties of Ho2Sn2O7 have been investigated and compared to other spin ice compounds. Although the lattice has expanded by 3% relative to the better studied Ho2Ti2O7 spin ice, no significant changes were observed in the high temperature properties, T greater than or similar to 20 K. As the temperature is lowered and correlations develop, Ho2Sn2O7 enters its quantum phase at a slightly higher temperature than Ho2Ti2O7 and is more antiferromagnetic in character. Below 80 K 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 approximate to 700 T.|
