| Research Abstract |
Supporting systems were established for promoting collaboration among 4 independent research projects ; 1. "Establishing novel methods for spin current generation and manipulation using metallic nano-structures", 2. "Electrical detection and control of spin current by using spin orbit interaction in semiconductors", 3. "Optimization of spin injection efficiency in silicon based spintronic devices", "Theory of spin injection and accumulation in nano-hetero structures". To be more precise, we have organized 1) a shared data server, 2) a video conference system, 3) periodical meetings to exchange domestic and international research information and also support for travel to attend international conferences. By using above supporting systems, we successfully obtained demonstrative results on the intrinsic origin of spin Hall effects via collaboration between theoretical and experimental groups. Moreover the discussion at the international conferences promoted successful research collaboration of French and Japanese groups for the study of the extrinsic mechanism of the spin Hall effects, leading to an important achievement.
