| Outline of Final Research Achievements |
Iron-based superconductors, which are discovered in Japan, show high critical temperature, critical current and critical current densities. So they are expected to be used for superconducting wires and future application for high magnetic field. We have improved the processes for the synthesis of polycrystalline powders and for fabrication of superconducting wires. As a results, high critical current density of 38 kA/cm^2 under magnetic field of 10 T is realized in obtained superconducting round wire. This is the world record of critical current density in iron-based superconductors round wire at preset. Furthermore, by the evaluation of the effects of fabrication process on superconducting properties, we gave the hint for further increase of critical current in the wires.
