Abstract:

An investigation was made of the model for the microscopic origin of ferromagnetism in the transition metals. It is suggested that by regarding the d-electrons as wave packets distributed throughout the metal and interacting only with a small number of other wave packets those with very similar energy a theory intermediate between the itinerant electron and strong correlation theories is obtained. It has not yet been possible to provide a first principle derivation of such a model. The difficulties are essentially the same as those of providing a theory of the electron gas at intermediate densities there being no useful expansion parameter for a perturbation treatment. Nevertheless the usefulness of the model makes such a derivation well worth pursuing.
