Anomalous Hall Effect in Thick Co$_3$Sn$_2$S$_2$ Weyl Semimetal Crystals

Ferromagnetic Weyl semimetals with Kagome lattice structures exhibit a strong coupling between magnetism and topological band features. Co3Sn2S2 is a prime example, showing a giant anomalous Hall effect (AHE) driven by Berry curvature from the Weyl nodes. We investigated the temperature and angular dependence of Hall conductivity in thick Co3Sn2S2 crystals, aiming to distinguish between topological and conventional magnetic contributions. Our measurements reveal a robust Hall response even at low magnetic fields and temperatures above 77 K, suggesting a dominant topological origin and weak sensitivity to external conditions.
