摘要：

The inelastic-neutron-scattering technique was used to measure magnetic excitations of Ho3+ dimers in Cs3Ho2Br9. The usual phenomenological models failed to reproduce the observed energy spectra. An exchange-tensor formalism, on the other hand, which treats the Ho3+ ground state as an effective S=2 state, provides an excellent description of the observed energy splittings and intensities. © 1990 The American Physical Society.
