We have obtained the exact numerical results of the specific heat, the susceptibility and the correlation functions L,(T) and L,(T) for finite extended Hubbard rings at the large U limit. It is shown that the nearest neighbor interactions favor the ferromagnetic ordering. When the number of electron
