| Outline of Final Research Achievements |
We have used advanced micro spectroscopy, especially micro photoemission spectroscopy, to study the electronic structure (and local structure if necessary) of candidate materials of exotic superconductors, which had been difficult to be studied spectroscopically due to experimental constraints. One of examples, for a candidate material of the chiral d-wave superconductor, SrPtAs, we succeeded in directly observing the Fermi surface and band structure, and experimentally showed that StPtAs are indeed located in a parameter region where exotic superconductivity can be induced. We have succeeded in experimentally clarifying the electronic structure and local structure that have not been clarified so far for other superconductors. These results lead to understanding of the superconducting mechanism of each system. In addition, progress has been made in the synthesis of related superconductors.
