Abstract

Highly monodisperse elemental iron nanoparticles with varying sizes are analyzed for their oxidation and magnetic properties. Magnetic measurements show that the Fe-cores assumed magnetization values comparable to those of bulk material. The oxidation rate displays a universal logarithmic growth, which establishes electron tunneling as the main oxidation mechanism.
