Sensitivity of synchrotron radiation x-ray diffraction to the chemical ordering in epitaxial perovskite multilayers

Nemoz, Maud Dooryhee, Eric Hodeau, Jean-Louis

The present work shows that the chemical ordering in (BaTiO3/SrTiO3)(N) chemical-vapor-deposition-grown superlattices can be reliably estimated by synchrotron radiation x-ray diffraction (XRD). XRD (00l) diagrams for l=1-8 have been simultaneously simulated using a unique set of parameters describing the stack with a model based on periodic...

Synchrotron x-ray scattering evidence for interlayer structural coupling in (PbMg1/3Nb2/3O3)(1−x)/(PbTiO3)x superlattices

Lemee, Nathalie Dooryhee, Eric Bouyanfif, Houssny

We present evidence for in-plane coupling in relaxor PbMg1/3Nb2/3O3 / ferroelectric PbTiO3 superlattices [PMN(1−x)Lambda/PTxLambda]10. For constant superlattice wavelength Lambda=dPMN+dPT, we find that by varying the constituents thicknesses dPMN and dPT a significant effect is observed on the internal a1/a2 domain structure of the PT layers as...
