Abstract
Exchange-spring magnets, also known as exchange-coupled nanocomposite permanent magnets, are fascinating because they blend the high coercivity of a hard magnetic phase with the impressive saturation magnetization of a soft magnetic phase, all thanks to strong interfacial exchange coupling. Since Kneller and Hawig first proposed this concept back in 1991, the field has really taken off, diving into theory, micromagnetic modeling, materials processing, and various applications. This paper takes a closer look at the fundamental principles, design guidelines, fabrication techniques, characterization methods, notable material systems, and the potential applications of exchange-spring magnets. It particularly highlights strategies to enhance the energy product ((BH)_{max}) through careful microstructural control, interface engineering, and innovative material combinations, including options that don’t rely on rare-earth elements. The paper also addresses the challenges ahead and explores future directions for this exciting area of research.
