| Research Abstract |
In spintronics, development of the generation and detection methods of spin current is a very important issue. By the progress of microfabrication techniques in recent years, the lateral spin-valve devices have come to be realized and several reports on spin current detection have been reported. In this study, by detecting spin-polarized tunnel current locally with using a tip of scanning probe microscopy as one electrode of the lateral spin-valve devices, we aimed at two-dimensional mapping of the spin current distribution. We have developed scanning tunneling potentiometry(STP) which was essential for the spin detection.
