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.
