(a) The hybridization V dependence of the long-range antiferromagnetic correlations of itinerant electrons and of the localized electrons at U = 4.0 for various temperatures T = 1/5,1/10,1/20. (b) Finite-size scaling of the antiferromagnetic structure factors for the conduction band and localized band for various hybridization V = 0.5, 1.0, 4.0 at temperature T = 1/20. Long-range antiferromagnetic order only survive in the localized band for small hybridization V region.
