• To investigate the spin wave and the stability of the ferromagnetic Kondo lattice, we describe the state with S_z=S-1 and that with S_z=S-1/2 in terms of the variational wave function. In this model, it is found that the spin-wave spectrum does not differ appreciably from the RPA result, since the bottom of the individual-particle excitation lies in a relatively high energy region. In this article, the double exchange ferromagnet is discussed with the Nagaoka ferromagnetic state of U=∞ Hubbard model, with respect to the stability of the ferromagnetic state.
