While the stoichiometric compound with x = 1/3\r\nexhibits a single magnetic transition, samples with x ≤ 0.325 display two transitions with an\r\nanomalous Hall effect (AHE) emerging in the lower temperature phase. Here, we resolve the spin structure in each phase by employing a suite of magneto-optical probes that include the discovery of anomalous magneto-birefringence – a spontaneous time-reversal sensitive rotation of the principal optic axes. A symmetry-based analysis identifies the AHE-active phase as an anisotropic (2+1)Q state, in which magnetic modulation at one wavevector (Q) differs in symmetry from that at the remaining two. The (2+1)Q state naturally exhibits scalar spin chirality as a mechanism for the AHE and expands the classification of multi-Q magnetic phases.","lang":"eng"}],"OA_type":"green","language":[{"iso":"eng"}],"year":"2025","month":"07","title":"Anisotropic multi-Q order in CoxTaS2","oa_version":"Submitted Version","oa":1}
