二维（2D）货车德瓦尔斯（vdW）磁性材料由于其能将长程磁有序稳定到原子尺度，并具有开发具有独特功能的新型自旋电子器件的前景而受到人们的广泛关注。澄清的磁阻特性及其相关的基本磁配置是必不可少的二维VDW为基础的自旋电子器件。本文研究了Co掺杂对Fe_3GeTe_2磁性和磁输运性质的影响。磁输运测量揭示了一种不寻常的霍尔效应行为，其强度被Co掺杂大大改变，并归因于潜在的复杂自旋织构。目前的研究结果提供了一个线索，剪裁的基础相互作用所需的实现各种非常规的自旋纹理的二维VDW FM为基础的自旋电子学。
Two-dimensional (2D) van der Waals (vdW) magnetic materials have attracted a lot of attention owing to the stabilization of long range magnetic order down to atomic dimensions, and the prospect of novel spintronic devices with unique functionalities. The clarification of the magnetoresistive properties and its correlation to the underlying magnetic configurations is essential for 2D vdW-based spintronic devices. Here, the effect of Co-doping on the magnetic and magnetotransport properties of Fe3GeTe2 have been investigated. Magnetotransport measurements reveal an unusual Hall effect behavior whose strength was considerably modified by Co-doping and attributed to arise from the underlying complicated spin textures. The present results provide a clue to tailoring of the underlying interactions necessary for the realization of a variety of unconventional spin textures for 2D vdW FM-based spintronics.
