By using EPR and magnetic susceptibility measurements, the Cr ion distribution in the xCr2O3.(1-x)[70TeO2·25B2O3·5PbO] glasses with 0＜x≤20 mol% was studied. EPR investigation evidencedthe presence of Cr3+ ions in agreement with the experimentally obtained atomic magnetic moment values. For concentrations x≤3 mol%, the isolated Cr3+ ions coexist with those coupledby dipole-dipole interactions. For x＞3 mol%, the Cr3+ ions participate in superexchange interactions and are predominantly antiferromagnetically coupled.

Boro-germanate glasses containing copper, i.e., xCuO(1-x)[GeO2·B2O3] subjected to gamma irradiation, were studied by means of EPR. Comparisons were made with the xCuO·(1-x)[Na2B4O7] system. Irradiation induced centers were detected. These are: electron trapped at a hydrogen compensated germanium ion centers; boron oxygen hole centers and electron trapped at an oxygen vacancy centers. Strong dependence of the paramagnetic irradiation-induced centers concentration on the CuO content of the sample was evidenced.

Glasses of xFe2O3 (l-x) Na2B4O7 for 0.3≤x≤5 mol% have been studied by means of EPR. The distribution of Fe3+ ions in the vitreous network. as isolated and connected in clusters. depends on the impurity contents in the glass. A thermal treatment inducing the Fe3+ -rich phase separation ends at the sample crystallization, when performed at about 550℃, Weathering of glasses causes a Superficial alteration of their optical properties. It enters the bulk of the glass for powdered samples. As a result of gamma irradiation pararnagnetic hole centers were detected:the BOHC. the peroxy radical and the iron hole centers

The xmnO(100-x)[***] glasses were prepared with mnO concentration being in the range of 0≤x≤50 mole fraction and were investigated by EPR spectroscopy and magneticsusceptibility measurements. Octahedral symmetric sites tetragonally distorted were detected for x≤5 mole fraction mnO. Only mn2+ ions were identified in these glasses, involved in dipoledipole interactions
