STUDY OF THE ELECTRONIC PROPERTIES OF SOLIDS.
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.
