We report on our progress in the fabrication and characterization of high-Tc thin films prepared on the in-house grown single crystal LaGaO3 and LaAlO3 substrates. YBaCuO and BiSrCaCuO films were deposited using a chemical-spray technique and a dc-magnetron-sputtering process, followed by an ex-situ high temperature annealing. In the case of LaAlO3 substrates, both fabrication methods resulted in highly oriented films, characterized by very good superconducting properties. On the LaGaO3 substrates we succeeded in fabricating only BiSrCaCuO superconducting films.
