Abstract : Nanocrystalline and nanocomposite materials are polycrystalline materials with grain sizes of up to about 100 nm. This survey reviews the current state-of-the-art in nanoscale design of magnetic materials and identifies new opportunities for future research and applications of these systems. A variety of preparative techniques that lead to magnetic materials with nanometer dimensions are discussed. These techniques include chemical self-assembly processes as well as mechanical fabrication techniques. This is followed by a discussion of the structures. theory and modeling concepts, and novel physical properties with emphasis given to the differences between course and fine grained magnetic materials. Finally, there is a discussion of the current and potential applications of nanophase materials that are likely to fuel research into the coming decades.
