The effect of the strong Hund coupling on the magnetic property of the ground stateis studied based on the double exchange model. For one dimensional chains the groundstate is proved to have the maximum total spin. The effect of the Pauli principle isshown to destroy the ferromagnetic ground state by numerical studies of finite loops.The result is extended to a model with degenerate bands.
