Abstract

The low temperature behavior of powder Er2Sn2O7 samples has been studied by magnetic susceptibility, heat capacity, and neutron scattering experiments. We report here the presence of no magnetic ordering down to 100 mK. Anomalies in the heat capacity can be accounted for through an analysis of the crystal field spectrum observed by inelastic neutron scattering spectroscopy. These new measusrements on Er2Sn2O7 suggest a new lower bound for the frustration index of f=0CW/TN = 14/0.1 = 140, placing this compound into a highly frustrated regime.
