The presence of excited spins in ferromagnetic systems can change the potential energy of interaction between atoms. In a ferromagnetic anharmonic linear chain the deformation formed and the spin excitations can create a bound state which can move along the chain with constant velocity without changing its shape. The quantum‐mechanical treatment of the problem leads to a nonlinear Schrödinger‐like equation with nonlinearity of third and fifth powers which has soliton solutions.
