Surfactant-Templated Synthesis and Magnetic Properties of Ordered Nanostructured Fe₃O₄

Abstract:

Surfactant-templated synthesis of ordered nanostructured materials attracts more and more attention. In this paper, ordered nanostructured Fe₃O₄ powder was synthesized via a facile reflux method in ethanol-water media using sodium dodecyl sulphonate (SDS, C₁₂H₂₅SO₃Na) as template. XRD and VSM were used to characterize the ordered nanostructure, inorganic phase and magnetic properties. Results show that Fe₃O₄ powder is of an ordered nanostructure of 7.6 nm which was detected by SAXRD and the inorganic phase is composed of cubic Fe₃O₄ nanocrystals. VSM analysis shows that the ordered nanostructured Fe₃O₄ exhibits a two-phase structure and a soft magnetic property with a saturation magnetization of 40emu/g.
