The arrival of the 'information age' took most people by surprise - including scientists and technologists. Today, research on better, smaller, and faster ways to store and transfer information continues to grow, and growing fast within this scope is the field of magnetoelectronics. With its possibilities as a magnetic storage technology capable of overcoming the vulnerabilities of CMOS (complementary metal on oxide semiconductor), magnetoelectronics promises to be an important installation in the information era.

This book is devoted to an entirely new direction of the magnetoelectronics of millimetric waves in layered structures containing epitaxial ferrite films. End of chapter references provide additional background information on the topics discussed.

This book provides an up-to-date review of nanometer-scale magnetism and focuses on the investigation of the basic properties of magnetic nanostructures. It describes a wide range of physical aspects together with theoretical and experimental methods. A broad overview of the latest developments in this emerging and fascinating field of nanostructured materials is given with emphasis on the practical understanding and operation of submicron devices based on nanostructured magnetic materials.

This book combines the proceedings of Symposium Q, Magnetoelectronics-Novel Magnetic Phenomena in Nanostructures, and Symposium R, Advanced Characterization of Artificially Structured Magnetic Materials, both from the 2002 MRS Fall Meeting in Boston. The common focus is on artificially engineered nanostructured magnetic systems. The two symposia address new phenomena in magnetoelectronic applications, their preparation, and advanced methodology for characterization. Interest in nanomagnetism has been catalyzed by advances in two fields of research. 1) Advances in materials synthesis of structures whose length scales transcend magnetic length scales and open the possibility for creating materials with new magnetic properties. Such structures include interfaces, superlattices, tunneling devices, nanostructures, and single-molecule magnets. 2) Advances in sample characterization techniques for nano-magnetism which allow detailed exploration of structure-property relationships in nanostructured magnetic systems. The volume highlights current trends in both fields and offers an outlook for further advances and new capabilities.

The history of scientific research and technological development is replete with examples of breakthroughs that have advanced the frontiers of knowledge, but seldom does it record events that constitute paradigm shifts in broad areas of intellectual pursuit. One notable exception, however, is that of spin electronics (also called spintronics, magnetoelectronics or magnetronics), wherein information is carried by electron spin in addition to, or in place of, electron charge. It is now well established in scientific and engineering communities that Moore's Law, having been an excellent predictor of integrated circuit density and computer performance since the 1970s, now faces great challenges as the scale of electronic devices has been reduced to the level where quantum effects become significant factors in device operation. Electron spin is one such effect that offers the opportunity to continue the gains predicted by Moore's Law, by taking advantage of the confluence of magnetics and semiconductor electronics in the newly emerging discipline of spin electronics. From a fundamental viewpoine, spin-polarization transport in a material occurs when there is an imbalance of spin populations at the Fermi energy. In ferromagnetic metals this imbalance results from a shift in the energy states available to spin-up and spin-down electrons. In practical applications, a ferromagnetic metal may be used as a source of spin-polarized electronics to be injected into a semiconductor, a superconductor or a normal metal, or to tunnel through an insulating barrier.

This book undertakes an extensive exploration of manganese-based compounds, such as T1−xSrxMnO3 (T = La, Pr; x = 0.35, 0.25) using density functional theory and Monte Carlo simulations with a focus on understanding their electronic, magnetic, and magnetocaloric properties. Ba1−xSrxFeO3 (x = 0, 0.2) is also studied via different approximations, offering a comparative perspective. In addition, the book looks at the influence of magnetism using Monte Carlo simulations, revealing crucial parameters and examining the GdCrO3 system through DFT and Monte Carlo simulation, shedding light on recent experimental observations. Additionally, Monte Carlo studies investigate magnetic and magnetocaloric features of Sr2FeMoO6, La2SrMn2O7 bilayer manganite, perovskite ferromagnetic thin films' surface effects, and SmFe1−xMnxO3 perovskite. In essence, this book significantly advances our comprehension of magnetic and magnetocaloric phenomena across diverse materials and is well-suited for both experimentalists and computational researchers working in this field.
