| Outline of Final Research Achievements |
The recently discovered iron-based superconductors are attracting the attention of many researchers because they are forming a new family of high temperature superconductors. In this project, we have studied thin film growth of these materials and the fabrication of several superconducting junctions. We have improved significantly the film quality of NdFeAs(O,F), which has the highest transition temperature (Tc) among the iron-based superconductors discovered so far. For BaFe2(As,P)2, which has a somewhat lower Tc but very high crystalline quality, we succeeded in the growth of thin films for the whole composition range. Thin films of CaFe2As2-based materials were also grown for the first time. Using these thin films, we have fabricated grain boundary junctions, and studied the junction properties. A method to form a smooth CaF2 barrier for the fabrication of planar type junctions was developed, and we also studied the growth of stacked hetero-junctions based on BaFe2(As,P)2.
