YBa[sub 2]Cu[sub 3]O[sub 7] superconducting thin films were deposited on R-plane sapphire substrates with Yttria-stabilized zirconia buffer layer by laser ablation. The structure of the films was characterized by X-ray diffraction. Superconducting transitional temperatures as high as [ge]90 K and critical current densities up to 2.2 [times] 10[sup 6] A/cm[sup 2] (77 K) were achieved. The results of Auger depth profile showed that no obvious diffusion occurred between the substrate and the YBa[sub 2]Cu[sub 3]O[sub 7] thin film.
