摘要：
The nonlinear coupling among spin waves is taken into account to explain the observed spin excitation spectrum of CsNiCl3. We found that the continuum due to the two-magnon excitation processes gives large peaks and also significantly affects the one-magnon spectrum. This is due to both the frustration and the quasi-one-dimensionality, which are important in CsNiCl3-type antiferromagnets.
