Interdependence of elastic strain and segregation in metallic multilayers: An x-ray diffraction study of (111) Au/Ni multilayers J.Lattice-charge stripes and spectral weight near the fermi surface AIP Conf. O x ͑Bi-2201͒ multilayer was investigated by x-ray diffraction methods in order to investigate the effect of internal strain on structural modulation. In multilayered structure, the effect of internal strain is more prominent than in an aliovalent substitution, such as a substitution of La 3+ for Sr 2+ . X-ray reciprocal space mapping ͑XRSM͒ was taken on the -2 plane ͑cross-section XRSM͒ in order to estimate the lattice constants along the in-plane and out-of-plane directions, and -2 scan was used to verify the multilayered structure. Another XRSM method, plan-view XRSM, was employed to verify the in-plane symmetry of structural modulation on theplane. The structural modulation was observed on both the cross-section and plan-view XRSM. The lattice constants together with the modulation vector in multilayer were varied by the multilayer periods without any substitution in the original structure.
