| Outline of Final Research Achievements |
We have constructed a spin- and angle-resolved photoemission spectrometer using laser light with an energy resolution of 1.7 meV, which is the world best. The spin direction is three-dimensionally detected. By using the constructed spectrometer and the existing spin-resolved scanning tunneling microscopes for the atomic structure imaging and local electron tunneling spectroscopy, we have achieved the following results on the spin-related phenomena at surfaces. (1) spin-polarized surface electronic band structures of the spin-split bands due to strong spin-orbit interaction, of topological insulators and of Weil semimetals, (2) Control of photoelectron spin direction from spin-polarized surface states by linearly polarized laser light. (3) Local wave functions and magnetism of a few atomic layers of iron nitrides, and (4) Growth and magnetism of fcc iron films with a few atomic layer Mn films.
