γ-Fe₂O₃ oriented growth by surfactant molecules in microemulsion

γ-Fe₂O₃ nanoparticles, nanorods and multi-pod nanostructure were prepared via a surfactant-assisted process using sodium dodecyl sulfate (SDS) as oriented template. The most influential factors on γ-Fe₂O₃ shape control including the ratio of surfactant injection quantity in microemulsion and reaction time were both studied. The hysteresis loop was operated to show that magnetic properties of γ-Fe₂O₃ were strongly influenced by the morphology of the crystal. The routine entails the executable synthesis of the desired nanostructures with novel physical properties for applications in nanotechniques based on the matching adsorption of organic molecules on the special facet of anisotropic crystalline nuclei.
