    Structural and magnetic properties of MnO-B2O3–SrO glasses

    The Mn2+ ion distribution in different structural units in 2B2O3·SrO glasses was revealed by means of electron paramagnetic resonance measurements. Octahedral symmetric sites, tetragonally distorted, were detecte...

    EPR and magnetic susceptibility studies of Cr2O3–Bi2O3–GeO2 glasses

    Electron paramagnetic resonance (EPR) and magnetic susceptibility measurements have been performed on xCr2O3(1−x)[Bi2O3·GeO2] glasses with 0<x≤20 mol%. These data show that the chromium ions are in Cr3+ valenc...

    Cu2+ containing TeO2−B2O3−PbO glasses studied by EPR

    EPR absorption spectra of Cu2+ were investigated in vitreous matrices of the system [70TeO2-25B2O3-5PbO] over a wide range of concentrations. The detected absorptions are strongly dependent on the matrix composit...
