A synthesis procedure that allows us to obtain ZnO:0.3 at % 119Sn samples with Sn2+ ions on the surfaces of oxide particles containing structure-forming cations on tetrahedral sites is developed for the first time. Analysis of the 119Sn Mössbauer spectra of obtained samples does not confirm the existence of the localized magnetic moments at ZnO grain boundaries recently suggested in the literature.
