Its nanocrystalline character was proved on its surface under SEM (surface was formed of deposited nanoparticles) and in its volume using TEM (deposited nanoparticles were stacked up, creating columns). No signi cant iron oxide phases were observed in the transmission Fe Mossbauer spectrum measured at 5 K nor in the surface-sensitive Fe conversion electron Mossbauer spectrum measured at 293 K.
