OXIDE SUPERCONDUCTIVE LEAD AND MANUFACTURE THEREOF

摘要

PURPOSE:To improve the critical current density and the mechanical characteristic (bending characteristic) by laminating the stabilized metal layers and the oxide superconductor layers alternately in the radial direction. CONSTITUTION:The stabilized metal layers 11-14 and the oxide superconductor layers 15-17 are alternately laminated in the radial direction, and the oxide superconductor layers 15-17 consist of the flaky oxide powder aggregate having the ab surface in the longitudinal direction of the oxide superconductive lead. Consequently, the sectional area of the superconductor layers 15-17 per one layer is not large, and the strength of each oxide superconductor layer 15-17 is compensated by the stabilized metal layers 11-14 positioned on/under the oxide superconductor layers. Thereby, the oxide superconductor layers 15-17 can keep the flexibility eliminating the damage by the bending deformation, and the critical current density Jc of the oxide superconductor layer can be improved.
