The report consists of two parts and appendices. In part one, the relationship between microstructural and electrical properties of semiconducting glass systems was examined. The glass systems of primary concern were the amorphous chalcogenides and the transition metal phosphates. The As2Se3-As2Te3 glasses have been characterized microstructurally, compositionally, electrically and switching has been examined. The transition metal oxide phosphate glasses have also been microstructurally characterized as well as electrically characterized. This class of glasses has also been carefully characterized in a chemical manner. In part two, the magnetic properties of a series of transition metal phosphate glasses have been studied both experimentally and theoretically. A theoretical model for amorphous antiferromagnets such as these glasses has been proposed and tested. In addition, the advantages of magnetic experiments in studies of glass structure have been demonstrated.
