Growth and Characterization of Conductive SrRuO3 and LaNiO3 Multilayers on Textured Ni Tapes for High-Jc YBa2Cu3O 7-

Journal Article · · Journal of Materials Research
Power applications of high-temperature superconducting (HTS) coated conductors will require stabilization against thermal runaway. We have developed conductive buffer layers to electrically couple the HTS layer to the underlying metal substrate. The structure comprises the layer sequence of SrRuO{sub 3} (SRO) on LaNiO{sub 3} (LNO) on biaxially textured Ni substrates. We report baseline investigations of compatibility of SRO/LNO multilayer structure with processing of YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) and demonstrate biaxially textured YBCO films on conductively buffered Ni tapes. These YBCO coatings exhibit self-field J{sub c} values as high as 1.3 {approx} 10{sup 6} A/cm{sup 2} at 77 K, and the entire structure (HTS + conductive buffers + metal substrate) shows good electrical connectivity. These results demonstrate that SRO/LNO buffer layers may provide a basis for stabilized coated conductors.
