论文摘要
电荷转移在异质结构的界面上起关键作用，这可能会影响电子结构并最终影响材料的物理特性。但是，一旦界面形成，电荷转移很难在外部进行操作。在这里，我们报告了Fe3Gete2/CR2GE2TE6/FE3Gete2全磁性van der wa der Waals异质结构中的电荷电荷转移，可以利用这些异质结构，以选择性地修改顶部或底部Fe3gete2电极的磁性。定向电荷从金属Fe3gete2到半导体CR2GE2TE6显着修饰了Fe3Gete2的磁各向异性能量，从而导致了巨大抑制的强迫性。在这项研究中证明的铁磁体的电选择性控制可以刺激基于范德华磁体的旋转器设备的发展。
Charge transfer plays a key role at the interfaces of heterostructures, which can affect electronic structures and ultimately the physical properties of the materials. However, charge transfer is difficult to manipulate externally once the interface formed. Here, we report electrically tunable charge transfer in Fe3GeTe2/Cr2Ge2Te6/Fe3GeTe2 all-magnetic van der Waals heterostructures, which can be exploited to selectively modify the magnetic properties of the top or bottom Fe3GeTe2 electrodes. The directional charge transfer from metallic Fe3GeTe2 to semiconducting Cr2Ge2Te6 remarkably modifies magnetic anisotropy energy of Fe3GeTe2, leading to the dramatically suppressed coercivity. The electrically selective control of ferromagnets demonstrated in this study could stimulate the development of spintronic devices based on van der Waals magnets.
