Low Temperature Synthesis of Magnetite and Maghemite Nanoparticles
Journal of Nanoscience and Nanotechnology, 2007We report on the synthesis of iron oxide nanoparticles below 100 °C by a simple chemical protocol. The uniqueness of the method lies in the use of Ferrous ammonium sulphate (in conjugation with FeCl3) which helps maintain the stability of Fe2+ state in the reaction sequence thereby controlling the phase formation. Hexamine was added as the stabilizer.

Study on the Magnetorheological Properties of Maghemite-Kerosene Ferrofluid
Journal of Nanoscience and Nanotechnology, 2009As the ferrofluids are synthesized in a controlled atmosphere to Prevent oxidation of the magnetite phase; most reports of rheological properties have been derived from magnetite based ferrofluids. In this paper a ferrofluid based on iron oxide was synthesized by co-precipitation with air.

Crack patterns in superlattices made of maghemite nanocrystals
Physical Chemistry Chemical Physics, 2013Here, 11 nm γ-Fe2O3 nanocrystals characterized by a low size distribution of 5% and dispersed in chloroform are deposited onto a substrate as well-defined films. The film thickness is controlled by the initial concentration of the colloidal solution. After drying, the film shows a network of well-defined cracks.
