Na2Co2TeO6 is a candidate Kitaev spin-liquid, but the nature of its ground state remains controversial, as spurious non-Kitaev exchange interactions promote magnetic ordering. Here, neutron scattering and muon-spin rotation experiments indicate the presence of strong quantum fluctuations in the ground state, giving rise to a multi-domain zigzag antiferromagnetic order.
