摘要：

The results of susceptibility and neutron inelastic scattering measurements on the pyrochlore compound Tm2Ti2O7 are presented. The crystal-field ground state of the Tm3+ ion has zero spontaneous magnetization, and a virtually dispersionless crystal-held excitation is observed. It is concluded that the crystal-field interaction dominates the exchange interaction in Tm2Ti2O7 lifting the expected degeneracy of the frustrated ground state.
