摘要：

Electron paramagnetic resonance (EPR) and magnetic susceptibility measurements have been performed on xCr(2)O(3)(1-x) [Bi2O3 . GeO2] glasses with 0 < x less than or equal to 20 mol%. These data show that the chromium ions are in Cr3+ valence state and for x less than or equal to 5 mol% they are isolated or experience dipole-dipole interactions. For higher Cr2O3 content the Cr3+ ions participate to the dipole-dipole and superexchange type interactions.
