Wang Yilin¹, Huang Li², Du Liang³, Dai Xi^{1, †,}

Spin–spin correlation function and effective local magnetic moments as a function of crystal field splitting Δ for N = 1.05, 1.50, 1.90 at U/t = 4.90, J_z = 0.25U. (a) The spin–spin correlation function at τ = β/2 for upper orbital χ₁₁(τ = β/2), (b) the effective local magnetic moments for upper orbital , (c) the effective local magnetic moments for lower orbital , (d) the total effective local magnetic moments . The arrows indicate plateaus.
