Abstract
Evidence for solitons moving along the ferromagnetic chains in CsNiF3 has been obtained by inelastic neutron scattering. As predicted by Mikeska the scattering is found at low q, around zero energy. The soliton activation energy, 8m, is determined via the temperature and field dependence of the intensities (m is the effective mass of the quasiparticle soliton). At H=5 kG we find 8m/kB=27K in reasonable agreement with the predicted value, as is the energy width at q=0.1
