Abstract

Thin Y-Ba-Cu-O films with very good structural and superconducting properties have been successfully prepared on single crystal cubic LaAlO₃ substrates by DC magnetron sputtering and by chemical spray deposition. Reported films are substantially less granular with respect to those grown by the same method on "classical" ZrO₂ or MgO substrates. Microstructure properties were evaluated by microwave emission tests and microscopic structural investigations. The LaAlO₃ crystal has a relatively small dielectric constant and low high frequency losses, as opposed to the widely reported SrTiO₃ substrate, and is a promising substrate material for growing high quality epitaxial high-T_c superconducting films for microwave applications.
