摘要
One of the most intensely researched subjects in the development of YBa2Cu3O7-delta (YBCO)-based coated conductors is the methodology for achieving ever-sharper film texture on flexible metal substrates. This is a critical issue due to the intrinsic weak-link behavior that results in depressed critical current density (J(c)) in polycrystalline YBCO. Using ion-beam-assisted deposition of magnesium oxide, we have achieved YBCO texture on superalloy substrates approaching that on single-crystal oxide substrates. This advance has allowed us to fabricate coated conductor samples with J(c)s that are as high as for films on oxide crystals; for example, >2 MA/cm(2) (75 K, self-field) at a YBCO thickness of similar to1.5 mum.
