Description
Electron magnetic resonance (EMR) spectra of gadolinium-doped lanthanum oxide powders have been studied at room-temperature for Gd concentrations between 0.02 and 2.00 mol.%. The results suggest that Gd3+ ions occupy substitutional sites, that the EMR linewidth and intensity increase with increasing Gd concentration and that the range of the exchange interaction between Gd3+ ions is about 0.39 nm, much smaller than that of the same ion in other rare earth oxide
