A novel nonlinear influence of the magnetoelastic energy because of the epitaxial strain allows us to explain the spontaneous magnetization and the cubic magnetostriction of a molecular-beam-epitaxy-grown SmFe{sub 2} thin film. Under this scope, new crystal-field parameters A{sub 4} and A{sub 6} and exchange coupling parameter {lambda}{sub ex} have been found. These new parameters could account for the change of the energy balance in the spin reorientation transition and explain the softening it has with respect to the bulk case.
