Evolution of the local moments m c in the conduction band and m f in the local band with the increasing of the hybridization V at interaction U = 4.0 (a) and U = 8.0 (b) for various temperatures T = 1/5, 1/10, 1/20. The on-site interaction U has no significant effect on the moments formation. The m f is largest for small values of V , which minimizes the quantum fluctuations.
