Abstract:

Novel three-dimensional (3D) cage-like α-Fe2O3 nanostructures were successfully prepared by a template-free hydrothermal synthetic route. The characterization results indicated that the nanostructures were assembled by α-Fe2O3 nanoparticles. The assembled cage-like α-Fe2O3 nanostructures show weak ferromagnetic behavior at room temperature, and the corresponding values were higher than those of α-Fe2O3 nanoparticles reported in the literature.
