Anisotropic Nd 2 Fe 14 B/Fe 67 Co 33 nanocomposite thin films are successfully fabricated. The multilayer composite films comprise Nd‐rich shell‐enveloped Nd 2 Fe 14 B grains and a Fe 67 Co 33 phase. The strong (001) texture of the Nd 2 Fe 14 B grains and the presence of exchange‐coupled Fe 67 Co 33 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.
