Magnetic Characterizations of CoFe2O4 Nano-Particles Prepared by Different Wet-Chemical Processing Techniques
Nano-structured spinel ferrites are of great interest in fundamental as well as applied materials science. The ferrites have been extensively studied due to their wide technological applications. The materials synthesis technique is a decisive factor for its structural and physical properties. There are various techniques for preparation of spinel ferrites or ferro-spinels, such as high temperature dry ceramic method, co-precipitation method, sol-gel method, molecular precursor method, micro- emulsion method, microwave synthesis, sono-chemical synthesis, auto-combustion or flash combustion method, citrate precursor and polymeric precursor methods. The main objective of the present paper is to report comparative study of magnetic properties of nano-structured cobalt ferrite synthesized by various wet-chemical techniques.
