Nanoparticles of solid solutions in GdAlO3 — GdFeO3 system have been synthesized. Plots of crystalline sizes for GdAl1-xFexO3 series versus GdFeO3 composition have been constructed. The sizes of solid solution nanoparticles were shown to decrease in comparison to the sizes of nanocrystalline individual compounds. The observed regularities allowed us to assume the formation of nanocrystalline GdAl1-xFexO3 series with core-shell morphology.
Keywords: nanostructures, solid solutions, precipitation technique, non-autonomous phases, core-shell nanoparticles.
