磁特性的电场 (E) 控制开辟了替代磁场或电流激活来控制磁化的前景。具有垂直磁各向异性的多层已被证明由于其各向异性的界面起源而对电场的影响特别敏感。在这些系统中，电场效应最近已被应用于辅助磁化切换和控制磁畴壁（DW）速度。在这里，我们报告了电场在类似材料中的两个新应用：控制畴壁成核和停止电极边缘的 DW 传播。 (C) 2013 年美国物理研究所。 [http://dx.doi.org/10.1063/1.4798506]
The electric (E)-field control of magnetic properties opens the prospects of an alternative to magnetic field or electric current activation to control magnetization. Multilayers with perpendicular magnetic anisotropy have proven to be particularly sensitive to the influence of an E-field due to the interfacial origin of their anisotropy. In these systems, E-field effects have been recently applied to assist magnetization switching and control domain wall (DW) velocity. Here we report on two new applications of the E-field in a similar material: controlling domain wall nucleation and stopping DW propagation at the edge of the electrode.
