Abstract
AbstractThe Heisenberg ferromagnetic chain of spins interacting with the atomic displacement by exchange interaction modulation is considered. The soliton solution of the nonlinear equation for the amplitude of the spin deviations is obtained in the limit of small velocities (which is equivalent to the limit of large soliton localization size). The nonlinear term of the equation is caused by the spin‐lattice interaction and is formed by the spatial derivatives of the amplitude. The soliton energy is higher than the linear spin wave one.
