Keywords: 57Fe NMR | maghemite γ-Fe2O3 | magnetite Fe3O4 | nanoparticles

We have synthesized and studied monodisperse iron oxide nanoparticles of smaller than 10 nm to identify between the two spinel phases, magnetite and maghemite. It is shown that 57Fe NMR spectroscopy is a promising tool for distinguishing between the two phases.
