(color online) 〈 m d 2 〉 versus μ for various values of V. The parameters are chosen as β = 40t⁻¹, U = 1.6t, t₁ = 0.2t, t₃ = 0.1t, and ε_d −μ = −U/2. The lines from top to bottom are listed in the order of increasing V. Circles represent the results for “case A” and triangles for “case B”. The distinction of 〈 m d 2 〉 for a given value of V is determined by the interlayer hopping energies, and larger local moment is favored for smaller V.
