The quasi-two-dimensional antiferromagnet Co1/3NbS2 was recently reported to have a significant anomalous Hall effect. However, its controversial spin configuration has presented challenges in understanding the physical mechanism behind the AHE. Here, through an array of experimental probes, Gu, Peng and coauthors verify an intrinsic k-space Berry curvature as origin of the spontaneous Hall effect, and elucidate the ___domain-related magnetic reversal behaviours.
