Strong Kitaev Interaction in BaCo&sub(2) (AsO&sub(4))&sub(2) / P.A.Maksimov, [a.o.]. – Text : electronic // Physical Review Letters. – 2025. – Vol. 135, No. 6. – P. 066703. – URL: https://doi.org/10.1103/k1gq-k8m7.

The inelastic neutron scattering results and their analysis unequivocally point to a dominant Kitaev interaction in the honeycomb-lattice cobaltate BaCo&sub(2)⁢(AsO&sub(4))&sub(2). Our anisotropic-exchange model closely describes all available neutron scattering data in the material’s field-polarized phase. The density-matrix renormalization group results for our model are in close accord with the unusual double-zigzag magnetic order and the low in-plane saturation field of BaCo&sub(2)⁢(AsO&sub(4))&sub(2).
