Synthesis and magnetic properties of core-shell Fe70Co30@Ag dendritic nanostructures

► Core-shell Fe70Co30@Ag dendritic nanostructures synthesized using a two-step reduction method. ► The core-shell dendritic nanostructure is mainly caused by diffusion-limited aggregation model. ► This nanostructure is multifunctional due to the combination of magnetic and optical properties.
