The present work derives motivation from the so called surface/interfacial magnetism in core shell
structures and commercial samples of Fe3O4 and c Fe2O3 with sizes ranging from 20 to 30 nm were
coated with polyaniline using plasma polymerization and studied. The High Resolution
Transmission Electron Microscopy images indicate a core shell structure after polyaniline coating
and exhibited an increase in saturation magnetization by 2 emu/g. For confirmation, plasma
polymerization was performed on maghemite nanoparticles which also exhibited an increase in
saturation magnetization. This enhanced magnetization is rather surprising and the reason is found
to be an interfacial phenomenon resulting from a contact potential. |
