Chemical synthesis of Nd2Fe14B/Fe3B nanocomposites.
High exchange-coupled Nd2Fe14B/Fe3B nanocomposites were synthesized by an integrative procedure of thermal decomposition and reductive annealing processes. The molar ratio of the resulting products of Nd/Fe/B can be tuned by adjusting the raw material proportion. The as-prepared nanocomposites exhibited an exchanged coupled effect with a large coercivity of 11 100 Gs, enhanced remanence Mr of 42.0 emu g(-1), and Mr/M3T of 0.59.
