Supported ε and β iron oxide nanomaterials by chemical vapor deposition: structure, morphology and magnetic properties

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