Magnetic nanostructures have emerged as a novel class of materials being used in variety of applications such as ultra-high-density magnetic recording media, drug delivery, magnetic resonance imaging, sensing, hyperthermia, and catalysts. These magnetic nanostructures can be synthesized in various forms ranging from nanoparticles, nanoclusters, nanorods, nanowires, and nanotubes to the thin films and multilayers, depending upon growth conditions. During last decade, interest in magnetic nanostructures has grown exponentially being inspired by recent advances in nanostructure growth and characterization techniques from which various fascinating properties can be realized which were not observed in the bulk material. These distinct properties can be ascribed to the energies associated with various physical parameters; those are comparable with size of nanostructures. Control over these properties enables researcher to develop new concepts that...
