(a) ED results for the NN Kitaev-Heisenberg model. (b–e) ED results for our extended spin model, using MRCI g factors and NN couplings plus J2 = J3 = 0.25 meV. The clusters used in the ED calculations are also sketched. The reference site is indicated by a square and the numbers labeling various other sites are in direct correspondence with the numbered curves in the plots of 
. Yellow windows indicate the Kitaev SL region. (f ) Finite-size scaling analysis for the NN, second- and third-neighbor spin-spin correlation functions at H = 13.2 T.
