Abstract
The interactions between YBa2Cu3O7−δ superconducting films and ZrO2 substrates with different crystal orientations were investigated. Our results show that the crystal orientation of the substrate influences the orientations of the YBa2Cu3O7−δ crystals, whose c-axis have preferential orientations parallel to the surface of 〈100〉 ZrO2 substrates. The copper segregation in Y-Ba-Cu-O/〈ZrO2〉 films results from substrate reactions. Y, Ba, and Cu atoms diffusing into substrates were detected by AES and RBS techniques. A thin silver film evaporated on ZrO2 substrate as a buffer layer effectively slows down or eliminates the substrate interactions. The strong preferential c-axis orientation perpendicular to the substrate surface has been observed in the YBa2Cu3O7−δ /Ag/〈ZrO2〉 samples.
