Outline of Final Research Achievements

There has been increasing interest in the spin-orbit interaction of electrons in solids, that plays an essential role on realizing a variety of topological materials and spintronic functions. In this study, we investigated the electronic structures and the roles of spin-orbit interactions in various superconductors and topological semimetal candidate, by utilizing the spin- and angle-resolved photoemission spectroscopy that can directly obtain the information on energy, momentum, and spin of electrons.
