Abstract
This talk will review the application of the functional integral method to the theory of magnetic systems from a somewhat personal point of view. Some effort is made to discuss the technical difficulties and developments and to compare alternative approaches. The strength of the method is that it provides a mathematical formalism to describe a physical model discussed in section 2. The method is formulated in section 3 and an inherent ambiguity is discussed. The role of Coulomb interactions is described. Section 4 deals briefly with the coherent potential approximation (CPA) approach to the associated problem of electron motion in random fields. Some alternative approaches are mentioned. In section 5 the results of calculations on iron and nickel are reported and in section 6 some conclusions are drawn.
John Hubbard died on November 27, 1980, and this paper has been prepared from his notes by D.M. Edwards
