Vemuru abstract: Synthesis and characterization of magnetic nanostructures is an important aspect of research in nanoscience. In order to improve the characteristics of nanomaterials based devices, it is important to understand the structure property relation as well as the mechanism of the magnetic ordering. In this talk, I will introduce magnetic nanostructured materials with applications in high density magnetic data storage. Some of these are rodlike metallic iron and g-Fe2O3 nanoparticles, PZT thin films with Co nanostructures, FeRhPd/Co thin films, core-shell structured FePt, FePtCu, and FePtAu nanoparticles. I will present the details of the nanostructural characterization using small angle neutron scattering, and the element specific magnetic moment determination using x-ray magnetic circular dichroism spectroscopy.
