The deposition and characterization of La2Zr2O7thin films deposited by metal-organic decomposition method on both single crystal SrTiO3and cube textured Ni-5 at.%W substrates are presented. Metal acetylacetonates in propionic acid solution was used. The results showed that LZO films are epitaxially grown with smooth surface with rms roughness around 2 nm. YBa2Cu3O7-δfilms, deposited by pulsed laser deposition technique on LZO buffer layers, showed critical temperature of 90 K and critical current density in self magnetic field Jc= 1.6 and 13 MA/cm2at 77 K and 4.2 K, respectively. A better Jcretention in magnetic field for YBCO films deposited on LZO/STO than YBCO on bare STO is observed indicating a rather strong vortex pinning as confirmed by microwave measurements.
