Structural and magnetic properties of strontium–borate glasses containing iron ions
Source abstract
Abstract
Glasses of the xFe2O3·(100 − x)[B2O3·SrO] system, with 0 ≤ x ≤ 30 mol%, were studied by EPR and magnetic susceptibility measurements. EPR spectroscopy and magnetic susceptibility measurements show that the Fe3+ ions are localized in sites of distorted octahedral symmetry and in clustered formations containing both Fe3+ and Fe2+ ions. Dipolar and superexchange interactions involving iron ions were revealed depending on the iron content of the sample.
