Description Core-shell Fe70Co30@Ag dendritic nanostructures were successfully synthesized via a simple transmetallic redox method at room temperature, employing a mixed Fe70Co30 nanoparticles, and AgNO3 solution. The Fe70Co30@Ag nanostructures demonstrate a leaf like structure with different lengths (100-300 nm) and widths (similar to 50 nm) connected to the main branch which is of several tens of mu m long. The Ag coating of thickness similar to 8 nm on Fe70Co30 enhances the plasmonic and antioxidation properties of Fe70Co30@Ag core-shell nanostructure. The saturation magnetization (M-S similar to 62 emu/g) and coercivity (H-C similar to 144 Oe) at room temperature clearly suggest that the Fe70Co30@Ag nanostructures is protected from the oxidation due to the Ag coating.
