Nanomaterials and Supramolecular Structures

Abstract

A synthesis technique of magnetosensitive nanocomposites was proposed on the basis of nanocrystalline magnetite (Fe3O4) or maghemite (γ-Fe2O3) and highly disperse silica. Thermogravimetry, differential thermal analysis, XRD, and a vibrating magnetometer were used to characterize prepared nanocomposites. It was found that nanosilica prevents growth of Fe3O4 nanocrystallites stabilized at average sizes of 5–8 nm.
