Effect of Electron Itineracy on Magnetism of S=1／2 Ferromagnetic Ising Model

The effect of electron itineracy on the magnetism of S=1/2 ferromagnetic Ising model is investigated by introducing a hopping term.The electron Green's function method is used to deal with this Hamiltonian.Here emphasis in made on that the magnetization is caused by the difference between the f...
