Abstract: The structural and magnetic propertiies of an oxide-fluoride mixe vitreous matrix 2B2O3•SrF2, were explored by using Fe impurities as probes. Information about the structural units involving iron ions, their valence state, the strengths and type of interactions involving them was obtained using EPR spectroscopy and magnetic susceptibility measurements.
