Magnetic Nanoparticles: Fabrication, Properties and Applications

Abstract

Magnetic nanoparticles are being widely used as potential materials in several applications, namely, consumer electronics, automobile and biomedical fields. Magnetic nanoparticles compacted in an insulating matrix are shown to be excellent materials for miniaturized high frequency electronic devices. Substituted cobalt ferrites and their self composites are increasingly found suitable for non-contact torque sensors. Functionalized magnetic nanoparticles and core-shell nanostructures would prove beneficial for biomedical applications. In this chapter, some simple preparation routes and common characterization techniques for the study of magnetic nanoparticles are covered. Further, recent advances and future prospects in all three application areas mentioned above are briefly discussed.
