Controlled growth and magnetic properties of α-Fe2O3 nanocrystals: Octahedra, cuboctahedra and truncated cubes

Author affiliations

Abstract

A series of α-Fe2O3 crystalline materials with fascinating polyhedral morphologies, such as octahedral, cuboctahedral and truncated cubic structures, were prepared through a novel solid-phase sintering process. Our results demonstrated that the structural transformations among the polyhedra were easily controlled by the sintering times. This suggested that the Wulff polyhedra transformation could occur in a hexagonal crystal system. Furthermore, we found that the magnetic properties of the α-Fe2O3 crystals were associated with their size and shape.
