Anisotropic Nd2Fe14B/Fe67Co33 nanocomposite thin films are successfully fabricated. The multilayer composite films comprise Nd-rich shell-enveloped Nd2Fe14B grains and a Fe67Co33 phase. The strong (001) texture of the Nd2Fe14B grains and the presence of exchange-coupled Fe67Co33 lead to a high remanence and the presence of the Nd-rich shell gives rise to a high coercivity. The unique nanocomposite microstructure provides hints for developing rare-earth-lean high-performance magnets.
