Nanoscale Magnetic Materials and Applications covers exciting new developments in the field of advanced magnetic materials. Readers will find valuable reviews of the current experimental and theoretical work on novel magnetic structures, nanocomposite magnets, spintronic materials, domain structure and domain-wall motion, in addition to nanoparticles and patterned magnetic recording media.Cutting-edge applications in the field are described by leading experts from academic and industrial communities. These include new devices based on domain wall motion, magnetic sensors derived from both giant and tunneling magnetoresistance, thin film devices in micro-electromechanical systems, and nanoparticle applications in biomedicine.In addition to providing an introduction to the advances in magnetic materials and applications at the nanoscale, this volume also presents emerging materials and phenomena, such as magnetocaloric and ferromagnetic shape memory materials, which motivate future development in this exciting field.Nanoscale Magnetic Materials and Applications also features a foreword written by Peter Grünberg, recipient of the 2007 Nobel Prize in Physics.

Explore novel solutions for energy-efficient refrigeration As climate change continues to impact the earth and how humans interact with it, new approaches to everyday processes are becoming ever more critical. According to some estimates, roughly 15% of the total worldwide energy consumption is related to refrigeration—air conditioning, refrigeration, freezing, or chilling. As the planet’s temperature continues to rise, these technological advances will only be more crucial. As it stands now, conventional cooling relies on a compression/expression refrigeration cycle, and as such is a high-energy-demanding industry. More, many chemicals used as refrigerants eventually enter into the environment, with increased global warming as a result. Magnetic Cooling offers an important alternative to traditional methods of refrigeration; heating metals when magnetized and cooling them when demagnetized allows for a system that is 20-30% more energy efficient than conventional cooling. Examining the most up-to-date research in this cutting-edge field, the book emphasizes both the properties of candidate refrigerants—from their fundamental magnetism to their machinability and processing—and the developments in regenerator, magnetizing magnet, and heat design. With an approach that covers essentially all aspects relating to key magnetic materials, this reference is a crucial resource to build towards a greener future. Magnetic Cooling readers will also find: A topic with direct impact on society as energy-efficient cooling is required both in domestic and industrial settingsContributions from leading researchers in every relevant sub-discipline presentedSections focused on the basics of the topic relating, such as magnetocaloric effect, thermodynamics of the magnetic cooling cycle, active magnet regenerators, and industrial synthesisFocused discussion of provisions necessary for this methodology, including raw materials, material analysis, and novel and nanoscale resourcesInformation on the state of the market, complete with industry comparisons and forecastsMagnetic Cooling is a useful reference for researchers working in magnetic materials, particularly those who work in physics, materials science, engineering, and chemistry. It will be of particular interest to refrigeration and air conditioning industry engineers.
