Superconductivity and Magnetism in Silicon and Germanium Clathrates,isrupted continuity of the framework. Efforts to produce analogous Ge-based superconductors have not been successful, due to the appearance of spontaneous vacancies, which also serve to disrupt the frameworks. The formation of these vacancies is driven by the Zintl mechanism, which plays a much more

Bit-Patterned Magnetic Recording: Nanoscale Magnetic Islands for Data Storage, begins with master pattern generation using electron beam lithography to create chemical contrast guiding patterns for self-assembly; this approach produces higher quality and higher density patterns than e-beam alone. Patterns are replicated over large volumes of disks by UV-cure nanoimprint litho

The Magnetic Microstructure of Nanostructured Materials,disorder which is reflected in the magnetization processes..In high-anisotropy materials with exchange-coupled grains in the 10?nm regime (exchange-enhanced nanocrystalline permanent magnets), a highly irregular domain structure is found, consisting of immobile and high-coercive patch domains. If ex

Exchange-Coupled Nanocomposite Permanent Magnets,conventional compaction techniques including warm compaction and dynamic compaction are recommended because they can be used to retain the desired nanoscale morphology for effective exchange coupling in the nanocomposites. At the end of this chapter, perspectives on fabrication of anisotropic nanoco

The chapter concludes with an overview of novel non-equilibrium processing routes used to obtain SmCo-type nanocomposites.

Growth and Properties of Epitaxial Chromium Dioxide (CrO2) Thin Films and Heterostructures,etic properties. The strain-induced magnetic anisotropy resulting from lattice mismatch with the substrates is also discussed. Finally, we provide some details regarding the fabrication of epitaxial rutile-based heterostructures and their transport properties in micron-sized tunnel junction and GMR
