摘要： The present invention concerns an enhancement of the supercurrent carrying capabilities of bicristalline or polycrystalline high- T c superconductors, i.e. the critical current densities in such superconductors. The current transport properties are improved by chemically altering, especially doping, the superconductors. It seems that a modification of the space-charge layers at the boundary, e.g. by an increase of the mobile charge carrier concentrations particularly in the superconductor's grain boundaries, which concentrations differ from those resulting in optimum superconducting properties of the grains, are responsible for this positive effect.

摘要： This invention concerns an improvement of the supercurrent carrying capabilities, i.e. the increase of critical current densities, of polycrystalline superconductor structures, especially of high -T?c? superconductors fabricated with a coated conductor technique to provide superconducting layers containing flat grains. A superconductor with superior critical current density is obtained by joining, i.e. pressing or otherwise bringing into intensive facial contact, preferably superconducting contact, two or more such superconducting layers.

摘要： The present invention concerns the improvement of the supercurrent carrying capabilities, i.e. the increase of critical current densities, of polycrystalline superconductor structures, especially of high-Tcsuperconductors. By modifying the microstructure of the substrate or by appropriately influencing the buffer layers in coated conductors to obtain grains with large aspect ratios which are predominantly oriented along the direction of the current flow, grain boundaries with large areas are obtained in the polycrystalline superconducting film that can support large critical currents along the superconductor. Thereby large critical currents are obtained in the superconductor for a given spread of misorientation angles of the grains.
