| Research Abstract |
Spin freedom is one of the most important aspect of electrons. Magnetic properties of materials and a new spin related phenomena caused by spin-orbit interaction can be understood by investigating the energy, momentum and spin of electron in solids.
To investigate electron spin one needs spin detector. Most popular spin detector is so-called Mott detector that is used all over the world so far. However, the efficiency of spin detection is very low. Recently we have developed a new spin detector called VLEED spin detector that has 100 times higher efficiency than the Mott detector. In this study we utilised two VLEED detectors and enabled to investigate the direction of spin vector as well as its spin polarization. Because of the high efficiency, 10 (5) times higher energy (angular) resolution in spin-resolved photoemission has been realised. This study opens a pathway to investigate spin properties of materials for the next generation spintronics devices very precisely.
