Quantum chemistry calculations on Na3Co2SbO6 show Kitaev and Gamma couplings antiferromagnetic but smaller than Heisenberg due to direct exchange and multiconfigurational effects.
Raman and EXAFS anomalies in SrLaCoNbO6 above its 15 K AFM transition are interpreted as evidence for spin-lattice coupling and proximate Kitaev-like correlations in a 3d Co2+ system.
Inelastic neutron scattering on Li₃Co₂SbO₆ is compared to linear spin wave theory to establish an extended Kitaev-Heisenberg model that identifies the material as a Kitaev A-type antiferromagnet.
