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...

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...
