Electric-field-driven magnetic switching——for future low-power magnetoelectric information devices

  • 摘要: 利用磁电耦合实现电场驱动磁翻转是多铁性材料领域的重要方向,有望用于大幅降低自旋电子学器件的能耗,并为解决日益增长的数据处理用电问题提供一种新方案。在过去几年,纯电控磁研究经历了曲折历程,取得一系列重要突破,包括纳米复合异质结构筑、应变耦合驱动电控180°磁翻转、界面磁交换耦合实现低电压驱动180°磁翻转,以及电场调控斯格明子磁性拓扑态等,为进一步开发超低能耗磁电存储或逻辑器件奠定了基础。文章聚焦于面向磁电信息器件的纯电场调控磁翻转,并简要回顾近十年来这一分支领域的发展历程和重要进展,梳理该领域目前所面临的问题并展望未来研究方向。

     

    Abstract: Magnetic flipping driven by an electric field through magnetoelectric coupling is an important research direction in the field of multiferroic materials. It may be applied to reduce the energy consumption of spintronic devices, and could provide a new scheme to solve the problem of increasing power consumption in data processing. In the past few years, the development of pure electrical control of magnetism has experienced a tortuous course, but has also seen a series of important breakthroughs, including the fabrication of nanocomposite heterostructures, electrically controlled 180° magnetic flipping driven by strain coupling, low-voltage driven 180° magnetic flipping through interface magnetic exchange coupling, and electric field manipulated magnetic topology such as skyrmions, which have laid the foundation for further development of ultra-low energy consumption magnetoelectric storage or logic devices. This paper focuses on the pure electric field regulation of magnetic flipping for magnetoelectric information devices, and briefly reviews the progress in the past decade, current problems in this field, and future research directions.
