(color online) 〈 m d 2 〉 versus μ for various values of U. The parameters are chosen as β = 40t, V = 1.0t, t₁ = 0.2t, t₃ = 0.1t, and ε_d −μ = −U/2. The lines from top to bottom are listed in the order of decreasing U. Circles represent the results for “case A” and triangles for “case B”. Larger local moment is favored for larger U, but the relative size of 〈 m d 2 〉 for “case A” and “case B” is determined by the choice of t₁ and t₃.
