EPR Structural Investigations on Ag2O-B2O3-CaO-P2O5 Vitreous System
Keywords:
EPR, glass, silverAbstract
Glass samples from vitreous system 1.5Ag2O98.5%[0.47B2O3(0.53-x)CaOxP2O5] with 0 £ x £ 0.08 have been obtained by undercooled method. The magnetic species existing in glass powders have been highlighting by mean of electronic paramagnetic resonance (EPR). The resonance linewidth analysis reveal the interactions between magnetic ions.
