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-Tc superconducting films for microwave applications.
