Abstract

About phase: Ferromagnetic γ-Fe2O3 nanowires (left in the figure) with a saturation magnetization (Ms) of 54.0 emu g−1 and coercivity of 518 Oe at room temperature, and superparamagnetic hollow α-Fe2O3 nanoparticles (right) with a room-temperature Ms of 2.9 emu g−1 were synthesized by the thermal decomposition of [Fe(CO)5] but with the stabilizing action of maleic anhydride grafted polypropylene.
