基于磁畴壁的信息存储和逻辑处理的概念在未来的信息和通信技术中具有巨大的实施潜力。到目前为止,应用耗能磁场或散热自旋极化电流来操纵磁畴壁的需求限制了此类技术的发展。使用电压控制磁畴壁的可能性为克服这些限制提供了一种节能的途径。在这里,我们证明了电压感生的单轴应变导致了磁涡壁手性的可逆确定性转换。我们将讨论如何将这一功能应用于信息存储和逻辑处理方案,朝着在节能计算中实际实现磁畴壁迈出了重要的一步。
Concepts for information storage and logical processing based on magnetic domain walls have great potential for implementation in future information and communications technologies. To date, the need to apply power hungry magnetic fields or heat dissipating spin polarized currents to manipulate magnetic domain walls has limited the development of such technologies. The possibility of controlling magnetic domain walls using voltages offers an energy efficient route to overcome these limitations. Here we show that a voltage-induced uniaxial strain induces reversible deterministic switching of the chirality of a magnetic vortex wall. We discuss how this functionality will be applicable to schemes for information storage and logical processing, making a significant step towards the practical implementation of magnetic domain walls in energy efficient computing.
