Interest in research on nanoscale materials is steadily increasing: nano-structured magnetic materials exhibit new and interesting physical properties, which cannot be found in the bulk. Many of these unique properties have great potential for technical applications in magneto-sensors, bio-sensors, magneto-electronics, data storage, magnetic heads of computer hard disks, single-electron devises, microwave electronic devices, etc. Current research concentrates on device design, synthesis and the characterization of nanostructured materials. The contributions to this book concentrate on magnetic properties of nanoscale magnetic materials, especially on fabrication and characterization, and the physics underlying the unique properties of these structures and devices.

The papers in this volume are drawn from Symposium Q, "Magnetoelectronics-Novel Magnetic Phenomena in Nanostructures," and Symposium R, "Advanced Characterization of Artificially Structured Magnetic Materials," which were held December 1-5 at the 2002 MRS Fall Meeting in Boston, Massachusetts. The common focus of interest was on artificially engineered nanostructured magnetic systems. The two symposia discussed new phenomena in such systems that are interesting for magnetoelectronic applications, their preparation, and advanced methodology for characterization. Interest in nanomagnetism has been catalyzed by advances in two fields of research: (i) 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. (ii) Advances in sample characterization techniques for nanomagnetism allow detailed exploration of structure-property relationships in nanostructured magnetic systems. The symposia reviewed current trends in both fields, and provided a forum for discussions about the outlook for further advances and new capabilities.

The study of electromagnetic fields in the treatment of various diseases is not a new one; however, we are still learning how magnetic fields impact the human body and its organs. Many novel magnetic materials and technologies could potentially transform medicine. Magnetic Materials and Technologies for Medical Applications explores these current and emerging technologies. Beginning with foundational knowledge on the basics of magnetism, this book then details the approaches and methods used in the creation of novel magnetic materials and devices. This book also discusses current technologies and applications, as well as the commercial aspects of introducing new technologies to the field. This book serves as an excellent introduction for early career researchers or a reference to more experienced researchers who wish to stay abreast of current trends and developing technologies in the field. This book could also be used by clinicians working in medicine and companies interested in establishing new medical technologies. Each chapter provides novel tasks for future scientific and technology research studies. Outlines the basics of magnetism for enhanced understanding of its applications in medicine Covers novel magnetic devices as well as technologies still under development, including magnetic brain stimulation, biosensors, and nanoparticles for drug delivery Explores commercial opportunities and obstacles to market entry for new magnetic materials and technologies for the medical field
