Research Abstract

We have developed novel fabrication process of FeSe superconducting wires using structural transformation of the wire core. The hexagonal FeSe1.2, starting wire core, was packed into the Fe sheath. By annealing at high temperature, the core and Fe sheath reacted and the transformation from hexagonal FeSe1.2 to tetragonal FeSe superconductor. This novel PIT method allowed us to obtain FeSe superconducting wires with high-density core. Furthermore, during this project, we have discovered new BiS2-based layered superconductor Bi4O4S3 and REOBiS2 systems. To date, 11 superconductors related to the BiS2-based superconductors have been discovered all over the world.
