Fe-containing nanoparticles on the surface of silica microgranules
(2006) In Inorganic Materials 42(8). p.877-882- Abstract
We have prepared nanomaterials consisting of SiO 2 microgranules and Fe-containing nanoparticles on their surface and determined the size and composition of the nanoparticles. The nanoparticles are shown to have a core-shell structure (α-Fe core and γ-Fe 2O 3 shell). The α-Fe core and Fe 2O 3 shell are responsible, respectively, for the broad and narrow lines in the EMR spectrum of the nanoparticles. The magnetic properties of larger nanoparticles are dominated by the core, while those of smaller nanoparticles are dominated by the oxide shell.
