Voltage control of magnetism has been considered and proven to be an efficient actuation protocol to boost energy efficiency in a widespread range of spintronic devices. In particular, the study of voltage-induced changes in magnetism by the magneto-ionic effect has rapidly accelerated during the past few years due to the versatile advantages of effective control, non-volatile nature, low-power cost, etc. In this perspective, we briefly outline the recent research progress on the voltage-controlled magneto-ionic effect by using two representative dielectric gating materials [ionic liquids (ILs) and ionic conductors] in different functional solid-state heterostructures and devices, mainly including both the ferroic-order [ferromagnetic, ferroelectric (FE), and multiferroic] oxides and magnetic metal-based heterostructure systems. Within the framework of ferroic oxide heterostructures, we have also extended the IL control to FE materials, clarifying that FE properties can also be tailored by electrostatic and electrochemical methods. Finally, we discuss the challenges and future aspects of magneto-ionics, which would inspire more in-depth studies and promote the practical applications.

铁性异质结构中电压驱动的磁离子控制的新兴机会

磁场的电压控制已被认为并被证明是一种有效的激励协议，可以在广泛的自旋电子设备中提高能量效率。特别是，由于有效控制，非易失性，低功耗等多方面的优势，在过去几年中，由磁离子效应对电压引起的磁场变化的研究迅速加速。 ，我们简要概述了通过在不同的功能性固态异质结构和器件中使用两种代表性的介电门控材料[离子液体（ILs）和离子导体]来实现压控磁离子效应的最新研究进展，主要包括铁电体和有序的[铁磁，铁电（FE）和多铁性]氧化物和基于磁性金属的异质结构体系。在氧化铁异质结构的框架内，我们还将IL控制扩展到了FE材料，从而阐明了FE特性也可以通过静电和电化学方法进行定制。最后，我们讨论了磁离子技术的挑战和未来方面，这将激发更深入的研究并促进实际应用。
