Structure of buffer CeO2 and LaNiO3 layers prepared by method of pulsed laser deposition on textured Ni-Cr-W substrates

Abstract

The results of an investigation of the structure, composition, and topography of the surface of buffer layers of CeO2, LaNiO3, and CeO2 + LaNiO3 on nonmagnetic textured NiCr9.2W2.4 substrates with a cube texture, which were prepared by pulsed laser deposition, are presented. The substrates with a buffer layer of this composition can be of interest for growing thin films and heterostructures of a wide class of oxide compounds, including superconductors of composition YBa2Cu3O7 − δ (123).
