Spinel ferrites, an important class of complex oxides, are imperative worldwide for their well-known magnetic, electrical, optical, catalytic properties, which led tem to be useful in various applications. These can prepared through solid state, physical, and wet chemical methods. One difficulty associated with the preparation compositions spinel ferrite (e.g., AB2O4 where A B two different metal cations +2 +3 valence states, respectively) is fact that often individual oxides obtained as impurities desired composition. Mostly, ferrites crystallize into cubic phase, makes these isotropic difficult grow 1D structures like other anisotropic such hexagonal zinc oxide tetragonal titania.
