Polycrystalline samples of ZnO + x mol.% Nd2O3(x = 0 - 7.73) were prepared from the suspension of ZnO in Nd nitrate solutionwith following evaporation, drying and annealing at 1000_C. The samples werecharacterized by X-ray diffraction analysis and ESR spectra measurement. Theobtained samples have a two-phase structure with Nd2O3covering ZnO grains. The addition of Nd2O3 to ZnO resultsin a decrease of the unit cell volume of ZnO, a decrease in the strength of theESR band with g = 1.958 and a more pronounced asymmetry of this band. Theexperimental results are explained as due to the mutual interaction of bothcomponents of the mixture leading to a decrease in nonstoichiometry of both ZnOand Nd2O3. It is assumed that in the crystal structures ofboth oxides concentrations of native defects, i.e. Zn interstitials and oxygenvacancies in ZnO and Nd vacancies and oxygen interstitials in Nd2O3are decreased.
