Аннотация:Nanocrystalline Ce-substituted yttrium iron-gallium garnet Y2.5Ce0.5(Fe0.5Ga0.5)5O12 was obtained by a metal-organic gel combustion methodusing PVA as a fuel with subsequent calcining in vacuum at 700 ◦C. According to SEM and XRD data, an additional heat treatment in air led onlyto an increase in the crystallinity of the sample. The element composition and the phase purity were confirmed by X-ray fluorescence spectroscopyand X-ray powder diffraction, respectively. Mossbauer spectroscopy on ¨57Fe nuclei revealed the presence of only Fe3+ ions in the sample, whichcan be considered as indirect evidence of the absence of tetravalent cerium impurity.DOI 10.17586/2220-8054-2021-12-2-210-217
