Research Abstract |
It has been pointed out that domain walls in spin-induced ferroelectrics play an important role in enhancing their magnetoelectric coupling. In this research, we have observed a systematic change in dynamics of 90-degree domain walls in a series of Tb_<1-x> Dy_xMnO_3 by the dielectric measurements. Moreover, we have constructed that the magneto-optical measurement system for the detecting of the multiferroic domain structure.
