Recent results of experimental studies on magnetoelastic coupling in epitaxial monolayers are compiled and discussed in view of theoretical work. The observation of non‐bulk like magnetoelastic coupling in strained systems in experiment and theory is ascribed to an effective and strain‐dependent magnetoelastic coupling. It is described as a second‐order strain contribution to the energy density. We comment on the importance of inhomogeneous strain and of its relaxation for the magnetic anisotropy of nanostructures.
