The YBCO films on these CeO<sub>2</sub>-buffered substrates exhibited high critical current densities with an average of 3-5 MA/cm<sup>2</sup> at 77.3 K. Using CeO<sub>2</sub> buffer layers we could avoid the occurrence of undesired <i>a</i>-axis-oriented grains of YBCO on these substrates despite employing lower heating rates. The lattice constants of YBCO films, CeO<sub>2</sub> buffer and substrates were compared. It was found that both the YBCO films and CeO<sub>2</sub> buffer were elastically deformed.</div></div> </li> <li class='list-group-item border-0 py-3 px-0'> <div class='row g-0 align-items-center mb-2'><div class='col-12 col-md-3 fullRecLabelEnglish fw-bold mb-2 mb-md-0'><span class='text-muted small'>Keywords</span></div><div class='col-12 col-md-9 leftDirection leftAlign'>barium compounds; cerium compounds; critical current density (superconductivity); elastic deformation; high-temperature superconductors; lattice constants; superconducting thin films; yttrium compounds; LaAlO<sub>3</sub>; NdGaO<sub>3</sub>; SrTiO<sub>3</sub>; YAlO<sub>3</sub>; YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub>-CeO<sub>2</sub>-LaAlO<sub>3</sub>; YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub>-CeO<sub>2</sub>-NdGaO<sub>3</sub>; YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub>-CeO<sub>2</sub>-SrTiO<sub>3</sub>; YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub>-CeO<sub>2</sub>-YAlO<sub>3</sub>; c-axis-oriented epitaxial superconducting film preparation; cerium oxide buffer layers; elastic deformation; fluorine-free metalorganic deposition; high critical current density; lattice constants; perovskite-type single crystal substrates; temperature 77.3 K; <formula formulatype=$ ${rm CeO}_{2}$ buffer layer; MOD; perovskite-type substrate; superconducting films;
