摘要

在层状反铁磁（AF）V5S8 中进行了系统角度和平面输运研究。与铁磁（FM）系统相比，在这种反铁磁系统中，当霍尔角达到 0.1 时，会出现明显的反常霍尔效应（AHE）。它可以持续到 AF 转变以上的温度，并表现出很强的角场依赖性。相图显示了旋转外加磁场时的各种磁态。通过分析各向异性的传输行为，磁子贡献被揭示出来，并表现出明显的角度依赖性和自旋翻转消失线。观察到的突出平面霍尔效应和各向异性磁致伸缩表现出两重系统性的角度相关振荡。这些行为归因于自旋轨道耦合的散射，而不是非对称拓扑起源。我们的研究结果揭示了 V5S8 的磁性和电子的各向异性相互作用，为 AF 自旋电子传感器和器件提供了潜在的机遇。

Angular and Planar transport properties for antiferromagnetic V5S8

Systemically angular and planar transport investigations are performed in layered antiferromagnetic (AF) V5S8. In this AF system, obvious anomalous Hall effect (AHE) is observed with a large Hall angle of 0.1 compared to that in ferromagnetic (FM) system. It can persist to the temperatures above AF transition and exhibit strong angular field dependence. The phase diagram reveals the various magnetic states with rotating the applied field. By analyzing the anisotropic transport behavior, magnon contributions are revealed and exhibit obvious angular dependence with a spin-flop vanishing line. The observed prominent planar Hall effect and anistrpoic magnetoresisitivity exhibit two-fold systematical angular dependent oscillations. These behavior are attributed to the scattering from spin-orbital coupling instead of nontrivial topological origin. Our results reveal anisotropic interactions of magnetism and electron for V5S8 suggesting potential opportunities for the AF spintronic sensor and devices.
