Research Interests

His research fields are spin-transport, spin-generation and spin-detection in ferromagnetic/anti-ferromagnetic semiconductor nano-structures. He belongs to Hitachi Cambridge Laboratory and collaborates with the University of Cambridge, the Institute of Physics ASCR, the University of Nottingham, the National Physical Laboratory and others. His research activities incorporate fundamental as well as applied research, with an emphasis on spin-orbit coupling related effects. One of his main findings was the first experimental observation of the spin Hall effect in a two-dimensional electron gas. It was announced in Physical Review Letters in February, 2005 and has more than 400 citations, and was later adapted to Physics Today. In addition, in 2006 we confirmed the “Coulomb Blockade” anisotropic reluctance effect that increases resistance by over 100 times. In 2010, we also successfully controlled and observed a spin-current same as an electrical current. These results will clear the way for the development of novel spintronics devices (devices which take advantage of their magnetic moment as well as their electrical properties).
