Abstract: With the development of energy and environment related technologies, nanomagnets with high magne-tocrystalline anisotropies as building blocks for next-generation permanent magnets are highly required. Advances in chemically synthetic steps towards rare-earth based magnets, nanocomposite structures for exchange-coupled magnets with enhanced energy products are discussed.
