Research Abstract |
To control magnetism and magnetization direction by electrical means is main purpose of this research. By using ferromagnetic semiconductors, an electric-field induced ferromagnetic phase transition and magnetization switching have been achieved. Furthermore, we observed ferromagnetic phase transition by applying an electric field even in a ferromagnetic metal for the first time at room temperature.
