| Outline of Final Research Achievements |
We utilized Fe-based layered superconductors. In the project, robustness of superconductivity for ferromagnet, amplitude of Hc of the layer superconductor equipping ferromagnetic films with perpendicular magnetization, and spin detection in Weyl semimetal that can exhibit superconductivity are realized. At the final stage of the project, we obtained an experimental result that suggests successful detection of spin polarization in the layered superconductor.
