Neutron Diffraction Study on Preferred Orientation of Ag-Sheathed Y-Ba-Cu-O Superconductor Tape with Jc=1000–3000 A/cm2

Abstract
Ag-sheathed tapes using tetragonal phase of YBa2Cu3O x were fabricated by cold rolling. Neutron diffraction study was undertaken to investigate the orientation of YBCO grains in the Ag-sheathed tape. It was clearly observed that the c-plane of crystal was aligned parallel to the cold rolling surface with a standard deviation of 26.7 degree. The preferred orientation was enhanced by using the tetragonal phase.
