A convenient two-step bottom-up approach for developing Au/Fe3O4 nanocomposites with useful optical and magnetic properties

Au/Fe3O4 nanocomposites were successfully synthesized using a two-step bottom up approach under co-precipitation followed by solvothermal synthesis without using capping agents or additives. TEM results indicate that nanocomposites with less agglomeration and high monodispersion can be obtained even in the absence of additives or capping ligands.
