Abstract
The structure, optical and electrical properties of manganese borosilicate glasses of the composition xMnO–(80 − x)SiO 2 –20B 2 O 3 (x = 40, 50, and 60 mol%) were investigated. The dependence of the glass structure on its composition was discussed and related to electrical properties. A separation of two amorphous phases was observed. It was suggested that one phase is MnO-rich and the other is SiO 2 -rich. It was found that the conductivity of MnO-rich phase is much higher than the conductivity of the other phase. The analysis of the valence states of manganese suggest that the transition metal ions are mainly present at second oxidation state. Magnetic susceptibility measurements show antiferromagnetic interactions in samples.
