A survey was made of the structure, electrical and magnetic properties of transition metal oxide phosphate glasses and glasses of the As2Te3-As2Se3 system. Results of magnetic and electrical observations in several transition metal phosphate glasses have revealed a high degree of magnetic and structural order. Examination of a representative group of transition metal phosphate glasses in a Cobalt 60 radiation source has revealed a pronounced effect upon the DC conductivity of these glasses. Detailed studies of the conduction process in copper phosphate glasses have revealed a mixed conduction mechanism of ionic and electronic mechanisms. This mixed conduction changes to exclusively electronic with thermal treatments which slightly densify the glass.
