Abstract: Electronic paramagnetic resonance and magnetic susceptibility measurements revealed the chromium ions distribution and interactions involving them in xCr2O3 (100-x) [70TeO2 25B2O3 5SrO] glasses within 0 < x <=10 mol %. The only detected valence state was Cr3+. Depending on the Cr2O3 content of samples the preponderance of Cr3+ ions identified as isolated in strongly distorted octahedral symmetric sites, or associated in exchange coupled pairs was pointed out. | |||||||
