A “Mechanical Aligning” Method for Preparing High-Jc YBa2Cu3Ox Superconductors

Abstract
High-J c YBa2Cu3O x ceramic samples were prepared by a mechanical aligning method which involved of large crystal growing and vibration aligning. In these samples, the crystal grains were found to be highly oriented and closely packed. Accordingly, the maximum critical current density was found to be 4200 A/cm2 at the liquid nitrogen temperature.
