| Outline of Final Research Achievements |
We have studied dynamical magnetic and electric responces for microscopic models of strongly correlated electron systems, in particular Mott insulators. We have investigated magnetoelectric interactions which appear in these models. We have also tried to predict and design novel dynamical magnetoelectric phenomena through these interactions.
From the interference of the dynamical electric and magnetic response caused by incident electromagnetic waves, we investigated characteristic dynamic response , such as non-reciprocal direction dichroisms. From a microscopic model , we derived novel magnetoelectric interactions in non-collinear spin systems. We focused on the skyrmion phases as a novel spin structure which causes a dynamic electric magnetic phenomena, to examine their dynamical natures and to discuss the control of spin textures.
