Abstract

One-dimensional (1D) nanostructures have attracted extensive attention due to their novel magnetic properties which are greatly dependent on nanorod size and shape [1]. If the particle size decreases toward a critical value it can consist of a single magnetic domain. Further, a 1D magnetic nanostructure can exhibit much higher coercivity than its isotropic counterpart because of the effect of shape anisotropy. Ferromagnetic hematite (α-Fe2O3) is of particular interest because of its low cost, high resistance to corrosion and environmentally friendly properties. Hydrothermal synthesis (HS) is a comparatively simple process for the preparation of 1D iron oxide nanostructures. However, the mechanism of nanorod formation is not clearly understood, thereby preventing the effective control of α-Fe2O3 nanorod size, shape and growth. α-Fe2O3 nanorods offer many opportunities with applications in fields such as drug delivery, gas sensors and magnetic data storage.
