Epitaxial growth and properties of YBa2Cu3Ox‐Pb(Zr0.6Ti0.4)O3‐YBa2Cu3Ox trilayer structure by laser ablation

We have grown YBa2Cu3Ox‐Pb(Zr0.6Ti0.4)O3‐YBa2Cu3Ox multilayer structure on SrTiO3 and Al2O3 substrates using laser ablation. The deposition conditions for the growth of trilayers and their properties are studied in this investigation. Scanning electron microscope images and x‐ray diffraction analyses indicate that all the constituent films in the trilayer grow epitaxially on SrTiO3 and were highly oriented on Al2O3. Transport measurements on these multilayers show that top YBa2Cu3Ox films have good superconducting properties.
