Exchange-coupled nanocomposites of Nd2 Fe14 B/[small alpha]-Fe are successfully synthesized by thermal decomposition and reductive annealing process. The phase size, composition, as well as magnetic properties, can be readily tuned by changing the ratio between Nd-Fe-B-oxide and [small alpha]-Fe. The optimum properties shows coercivity of 12 000 Gs and an enhanced remanence of Mr /M3T = 0.63.
