Abstract
The chemical shift in cristalline and amorphous Cr2O3 was determined f rom the X-ray absorption Cr K edge spectra. The measurements of the te mperature dependence of the reciprocal susceptibility between 100 and 1200 K show an antiferromagnetic behavior for the cristalline sample, with the Neel temperature at 318 K, and a linear dependence (Curie-Wei ss law) with theta(p) < 0, for the amorphous oxide.
