EPR Study of Some Iron-Lead-Phosphate Glasses

The xFe2O3(1-42P2O5 PbO] glass system with 0.5x550 mol% was prepared and investigated by means of EPR spectroscopy in order to evidence the structural changes induced by the iron ions in different ratios. The isolated Fe3+ ions are situated in sites of distorted octahedral symmetries (rhombic or tet...

Zusammenfassung:The xFe2O3(1-42P2O5 PbO] glass system with 0.5x550 mol% was prepared and investigated by means of EPR spectroscopy in order to evidence the structural changes induced by the iron ions in different ratios. The isolated Fe3+ ions are situated in sites of distorted octahedral symmetries (rhombic or tetragonal). The dipolar and superexchange interactions were also revealed among iron ions as a function of Fe2O3 content of the samples.
