Lattice strain distributions mapped by high energy X-ray diffraction (see Figure) in an electrodeposited iron coating with nanocrystalline grains show high nonlinearity, providing unambiguous evidence for the existence of a strong stress interaction along the growth/deposition direction in a layered material.
