An anisotropic Heisenberg ferromagnetic chain is considered where the lattice deformation caused by the spin deviations is taken into account both, in harmonic and anharmonic approximation. The possibility of solitary bound formation between spin clusters and lattice deformation is investigated. It is shown that such a solitary “domain” can exist and propagate along the chain with constant velocity and without “smearing”. In this way a magnetic moment can be transferred without dissipation.
