Mean Field Theory of Magnetism of Metals: The Stoner Model,is quite different from that in an insulator; in the metal an electron outside of the closed shell of an atom can move around the entire volume, but in the insulator such a free motion of an electron is not possible. Correspondingly, the magnetic properties of a metal are quite different from that o

Electron-Phonon Interaction: The Effect of Magnetism on Lattice Vibrations, in a metal. We start our discussion by exploring how directly the magnetic property of a metal is reflected in its phonon spectrum and elastic property. A more thorough discussion of this subject based on the results of this and the next chapters will be given in Chapter 7.

The Role of the Electron-Phonon Interaction in Metallic Magnetism,eraction (EPI). In this chapter we discuss the opposite problem; we explore how phonons are involved in determining the magnetic properties of a metal through EPI. In the course of such endeavor we also review the basics of itinerant electron magnetism in general, with some new results.

In those discussions we used the equation of motion approach with the mean field approximation in dealing
