Abstract

We analyze fundamental issues related to the thermal and electrical stability of a coated conductor during its operation. We address the role of conductive buffer layers in the stability of Ni-based coated conductors, and the effect of a metallic cap layer on the electrical properties of Ni alloy-based superconducting tapes. For the first case we report on the fabrication of a fully conductive RABiTS architecture formed of bilayers of conductive oxides SrRuO ₃ and LaNiO ₃ on textured Ni tapes. For the second case we discuss measurements of current-voltage relations on Ag/YBa ₂Cu ₃O _7-δ and Cu/Ag/YBa ₂Cu ₃O _7-δ prototype multilayers on insulating substrates. Limitations on the overall tape structure and properties that are posed by the stability requirement are presented.
