Description
Electron microscopic investigation into YBa2Cu3O7-δ films on (100) SrTiO3, (110) SrTiO3, ZrO2/Si, ZrO2/α-A2O3 substrates produced by laser spraying, technique are conducted. A strong substrat effect on the film structure is detected. In case of SrTiO3 substrate application an epitaxial film growth is observed. The mechanism of orientation of polycrystalline films on Si- and α-Al2O3 substrates with polycrystalline ZrO2 buffer layers consists in anisotropic substrate stresses. ΔTC critical transfer width increase and JC critical current density reduction are linked with a large number of defects in grains, the presence of supplementary phases and defects on intergranular boundaries
