摘要

Inelastic neutron-scattering (INS) experiments were performed to investigate the spin dynamics in magnetoelectric effect LiCoPO_4 single crystals. Weak dispersion was detected in the magnetic excitation spectra along the three principal crystallographic axes measured around the (0 1 0) magnetic reflection. Analysis of the data using linear spin-wave theory indicates that single-ion anisotropy in LiCoPO_4 is as important as the strongest nearest-neighbor exchange coupling. Our results suggest that Co~(2+) single-ion anisotropy plays an important role in the spin dynamics of LiCoPO_4 and must be taken into account in understanding its physical properties. High-resolution INS measurements reveal an anomalous low-energy excitation that we hypothesize may be related to the magnetoelectric effect of LiCOPO_4.
