我们提出了一种方法来全电控制的畴壁位置的铁磁纳米线与Dzyaloshinskiii-Moriya相互作用。这种相互作用的强度可以通过外部电场来控制,这反过来又允许微调自旋螺旋畴壁的钉扎电位。它允许创建更多的移动的钉扎位点,并且对于超低功率电子器件也可以是有利的。
We propose a method to all-electrically control a domain-wall position in a ferromagnetic nanowire with Dzyaloshinskii-Moriya interaction. The strength of this interaction can be controlled by an external electric field, which in turn allows a fine tuning of the pinning potential of a spin-spiral domain wall. It allows to create more mobile pinning sites and can also be advantageous for ultra-low power electronics.
