Theory of Ferrimagnetic Insulators, Alloys and Magnetic Impurities.

Abstract

The electronic structure of uranium ions in insulating host materials has been determined, enabling one to explain the magnetic behavior of the uranium iodide and oxide compounds. The optical properties of the laser ion, chromium, in GdAlO3 have been explained. The cause of the anomolous behavior of the magnetic susceptibility of Ce compounds has been understood. The behavior of helimagnets in magnetic fields has been studied and the phase diagrams in external magnetic fields have been constructed. The electronic conductivity of a one-dimensional model for a substitutional alloy and of a multilayer semiconductor has been determined. Finally, new methods for the solution of the transport equation in solids have been developed and applied in the areas of heat transport through insulators and neutron transport through reactors.
