Raman spectroscopy has been used to get some insight into the chemical composition and structure of magnetic uids based on ferrites. The inner as well as the surface structure of Fe-maghemite and Zn-maghemite have characterized by Raman spectroscopy. It has been shown that di erent chemical species are present on the maghemite surface by changing the laser excitation energy. Maghemites modi ed by the adsorption of aspartic and glutamic acids as well as those modi ed by the adsorption of… CONTINUE READING
