| Outline of Final Research Achievements |
Recently, it has been theoretically predicted that there can be a local spin polarization state, which is induced by spin-orbit interaction and local symmetry breaking, even in materials possessing centrosymmetry. However, in such materials, there must be the site which is possessing opposite spin-polarization, it is necessary to do site selective measurement to observe the local spin-polarized electronic states experimentally. In order to investigate the electronic state of such novel spin-polarized materials, in this study, we have developed a new spin- and angle-resolved photoelectron spectroscopy system utilizing the focused laser beam (~10 micron) as the excitation light. Since the intensity of the focused beam is low and spin-polarized photoemission measurement is inefficient, we have also developed a multi-channel spin- detector which can improve the measurement efficiency more than 1000 times higher than the normal single channel spin detector.
