Abstract

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 Nd ₂Fe₁₄B grains and the presence of exchange-coupled Fe ₆₇Co₃₃ 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.
