| Outline of Final Research Achievements |
An ink-jet printer was applied to introduce flux pinning centers into YBa2Cu3Oy superconducting films as a new approach for deposition technique. The ink-jet printing technique is particularly interesting and effective to fabricate films and/or their patterns because it is a non-contact technique to the substrates. The starting solutions for fabricating superconducting film were packed in the ink cartridges of the printer, and the projected drop of ink traveled through air to the substrate.
As the results, it was succeeded in fabricating the superconducting films and introducing BaHfO3 flux pinning centers into the films with optional form and shape. The obtained films showed crystal grain alignment to c-axis. Also, flux pinning centers were arrayed as line-shape into the film to the parallel direction for electric current with a diameter of about 50 um.
