N2 - The results of a detailed inelastic neutron scattering study of the spindynamics in CsNiF3 in an external magnetic field are presented. Results have been obtained for different combinations of the correlation function (α=x, y, z) in order to analyse theH, T, q c-dependence of both, the central component and the spinwave scattering. These results cannot be explained by a multispin-wave theory alone, but it is necessary to introduce solitons in order to describe the experimental findings. It is found that under certain conditions the contribution from solitons and from two-spinwave processes have the same size. These results show that the spindynamics in this system in fields 2.5kOe15K this picture breaks down probably due to the finite size of the easy plane anisotropy energy.
