论文摘要
二维（2D）Van der Waals（VDW）磁性材料引起了很大的关注，这是由于远程磁性稳定下降到原子维度，以及具有独特功能的新型纺纱设备的前景。澄清磁化特性及其与基础磁性构型的相关性对于基于2D VDW的自旋设备至关重要。在这里，已经研究了共掺杂对Fe3gete2的磁和磁转移特性的影响。磁转运测量结果揭示了一种异常的大厅效应行为，其强度通过共同掺杂而大大改变，并归因于基本的复杂自旋纹理。目前的结果为实现2D VDW FM基于2D FM的Spintronics所必需的基本相互作用提供了一个线索。
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.
