Magnetization curves and spin-structure factors for α-RuCl₃.

(a) 24-site cluster with PBC’s used in the ED calculations. (b) Experiment³⁰ vs ED plots using MRCI g factors and NN couplings plus J₂ = J₃ = 0.25 meV. (c) ED magnetization curves with J = 1.0, K = −5.0, J₂ = J₃ = 0.3, g_ab = 2.4, g_c = 0.95 and vanishing off-diagonal NN couplings. (d) Field dependence of the NN, second- and third-neighbor spin-spin correlation functions extrapolated to the thermodynamic limit, using MRCI g factors and NN couplings, J₂ = J₃ = 0.25 meV and field along the c axis. Static spin-structure factors S(Q) are shown for (e) H = 0, (f) H = 9.5, (g) H = 10.5 T.
