Abstract

We report on the epitaxial growth of LaTiO₃ on biaxially textured (0 0 1) Ni. This investigation centers around the potential use of (La,Sr)TiO₃ as a conductive buffer layer for subsequent growth of high temperature superconducting films for coated conductors. Epitaxy of LaTiO₃ on Ni is achieved using pulsed-laser deposition. Excellent in-plane and out-of-plane alignment is confirmed via X-ray diffraction. For undoped LaTiO₃ films, the oxide/metal interface is not stable against substrate oxidation, reflective of the propensity of LaTiO₃ to accommodate excess oxygen in the lattice. Future work will focus on Sr-doped LaTiO₃ films as this should alleviate these limitations.
