Angular and planar transport properties of antiferromagnetic V₅S₈

Abstract

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.
