Magnetic and structural behaviour of xEu2O3(1−x)(3Bi2O3 PbO) glasses

Abstract Glasses of the x Eu 2 O 3 (1− x )[3Bi 2 O 3 ·PbO] vitreous system with x = 0 – 0.30 were studied using magnetic susceptibility, electron paramagnetic resonance and IR spectroscopy measurements. Magnetic susceptibility data indicate the presence of the europium ions in both their 2+ and 3+ valence states. The exchange interactions between the europium ions are predominantly antiferromagnetic. Magnetic and IR spectroscopic data suggest that the europium ions play both the network former and network modifier role in the studied glasses.
