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