Electrical control of magnetization

本研究的主要目的是通过电气手段来控制磁化和磁化方向。利用铁磁半导体实现了电场诱导的铁磁相变和磁化强度转换。此外，我们还首次在室温下通过在铁磁金属中施加电场来观察到铁磁相变。

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.
