We have studied the epitaxial arrangement of thin films and heterostructures of copper-oxide based isotropic metallic oxides-La6.4Sr1.6Cu8O20 (LSCO), and La4BaCu5O13 (LBCO)-using four-circle x-ray diffraction and atomic force microscopy. AU the films grow epitaxially `cube-on-cube' with respect to the substrate. The single layer LSCO films were found to be very smooth (RMS roughness = 5 Angstrom) with a 90 degrees rectangular grain structure. These films exhibit metallic conductivity and the bilayer La6.4Sr1.6Cu8O20/YBa2Cu3O7 (LSCO/YBCO) films show a sharp superconducting transition with T-c = 88.4 K. Due to their structural and chemical compatibility with YBCO, these materials can be ideal normal metal barriers in fabricating SNS junctions with high junction resistance and low interface resistance.
