Review on Important Magnetic Materials for Future Technologies

Magnetic materials are essential for future energy, transportation, electronics and information technologies. Conventional materials such as ferrites, Nd–Fe–B and Sm–Co magnets continue to play important roles, while new research is focused on rare-earth-free magnets, nanostructured materials, spintronic materials and two-dimensional magnetic systems.The major future challenge is to develop magnetic materials that combine high magnetic performance, low cost, thermal stability, environmental sustainability and recyclability. Rare-earth-free iron-based magnets and advanced ferrites are promising candidates. Continued research in nanotechnology, material synthesis, structural characterization, magnetic measurement and computational materials science will contribute to the development of next-generation magnetic materials.
