In this work we describe the microstructural features of YBa2Cu3Ox (YBCO) superconducting films, obtained by metal-organic deposition produced on different substrates: metallic (Ag and Cu), polycrystalline (Al2O3 and Y0.15Zr0.85O1.93) and single crystals(MgO(001), SrTiO3(001), LaAlO3(001), NdGaO3(001) and CaNdAlO4(001)). The samples were characterized by X-ray diffraction and scanning electron microscopy analyses. We observed that the YBCO film orientation is influenced by the substrate nature: on single-crystal subtrates, YBCO films show a preferential (001) orientation. The alkaline-earth-rare-earth aluminates have proven an excellent choice for deposition.

Abstract
In this work we describe the microstructural features of YBa2Cu3Ox (YBCO) superconducting films, obtained by metal-organic deposition produced on different substrates: metallic (Ag and Cu), polycrystalline (Al2O3 and Y0.15Zr0.85O1.93) and single crystals(MgO(001), SrTiO3(001), LaAlO3(001), NdGaO3(001) and CaNdAlO4(001)). The samples were characterized by X-ray diffraction and scanning electron microscopy analyses. We observed that the YBCO film orientation is influenced by the substrate nature: on single-crystal subtrates, YBCO films show a preferential (001) orientation. The alkaline-earth-rare-earth aluminates have proven an excellent choice for deposition.
