Supported ε- and β-Fe2O3 are synthesized by a chemical vapor deposition (CVD) strategy, yielding systems with controllable morphologies from nanorods (ε) to square-like pyramids (β). The hard magnetic properties of ε-Fe2O3 and the antiferro/paramagnetic behavior of β-Fe2O3 are directly influenced by the system morphological organization and structural orientations.
