| Outline of Final Research Achievements |
In this research project, orientation behaviors of REBa2Cu3Oy superconductor particles under modulated rotating magnetic fields (MRFs) and their twin microstructures were clarified. Based on these, Directions to fabricate REBa2Cu3Oy superconducting materials with higher orientation degrees were obtained in both aspects from the crystallochemistry and MRF conditions. Moreover, a sintered sheet of biaxial oriented DyBa2Cu3Oy has been successfully fabricated and, however, its critical current density was low due to insufficient intergrain connection. Although there are issues to overcome, we found the magnetic alignment was a good candidate of production process of superconducting materials with both of high orientation degrees and large cross sections.
