Our aim is to explore novel spin-related effects with extremely high efficiency in condensed matters. We thus contributes to development of spintronics, a technology using spin as well as charge of electrons, and to realization of ultrafast and high-density information technology with low energy consumption. Our particular interest is at present in a strong quantum relativistic effect in solids, which is applicable to very strong magnets and efficient conversion of spin information to an electric signal. Our main method is a field theory.
