MAGNETIC SUSCEPTIBILITY STUDY OF B2O3BaO GLASS MATRIX DOPPED WITH IRON IONS

Journal Title: Natural Resources and Sustainable Development - Year 2014, Vol 4, Issue 1

Abstract

EPR and magnetic susceptibility measurements have been performed on xFe2O3(1-x) [3B2O3BaO] glasses with 0 < x ≤ 50 mol%. The influence of a gradual increase in Fe2O3 content on the glass matrix (B2O3BaO) structure and magnetic interactions involved iron ions have been discussed. By EPR data, the Fe3+ ions in sites of distorted octahedral symmetry were evidenced. EPR and magnetic susceptibility results indicate that in studied glasses the iron ions participate at the dipolar or/and superexchange magnetic interactions. From magnetic data it was evidenced that the iron ions are in Fe3+ and Fe2+ valence state and are antiferomagnetic coupled, these are depending on the iron content of the glasses.
