Investigation of surface passivation process on magnetic nanoparticles by Raman spectroscopy

A detailed study of the surface passivation process in superparamagnetic cobalt ferrite nanoparticles has been carried out using micro Raman spectroscopy. In addition to Raman spectroscopy, X-ray diffraction and atomic absorption spectroscopy were also used to investigate passivated and non-passivat...
