| Research Abstract |
The aim of this study is to reveal the mechanism of exotic phenomena observed in multi-ferroic compounds by using advanced techniques related with transmission electron microscopy. Our research group has reported important results such as on the underlying mechanism of colossal magnetoresistance in manganites, domain switching phenomena induced by an applied electric field, and a new method that determines magnetic parameters in nanometer-scale area.
