PbO-Sb2O3-As2O3 glasses containing different concentrations of Fe2O3 (ranging from 0 to 1 mol% in steps of 0.1%) were prepared. Optical absorption, magnetic susceptibility and ESR spectral studies on these glasses have been carried out as a function of Fe2O3 concentration. The interesting changes observed in these properties are discussed in the light of various oxidation states of iron ions.
