Abstract: Nanoparticles of solid solutions in GdAlO$_{3}$ – GdFeO$_{3}$ system have been synthesized. Plots of crystalline sizes for GdAl$_{1-x}$Fe$_{x}$O$_{3}$ series versus GdFeO$_{3}$ 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 GdAl$_{1-x}$Fe$_{x}$O$_{3}$ series with core-shell morphology.

Keywords: nanostructures, solid solutions, precipitation technique, non-autonomous phases, core-shell nanoparticles.
