Layer-by-Layer Self-Assembled Ferrite Multilayer Nanofilms for Microwave Absorption

Figure 1

TEM images of (a) synthesized OA-stabilized Co_0.5Zn_0.5Fe₂O₄ ferrite nanoparticles, and (b) ligand-exchanged bPEI-Co_0.5Zn_0.5Fe₂O₄ ferrite nanoparticles. Inset images show the ferrite nanoparticles from the respective treatments that (a) precipitated in water and (b) dispersed in water. (c) XRD patterns of powdered OA-stabilized Co_0.5Zn_0.5Fe₂O₄ nanoparticles.
