The effects of a partial substitution of Ga for Fe on the structure and magnetic properties of mechanically alloyed Nd8.4Fe87.1B4.5 were studied. With increasing Ga content, the magnetic properties of the nanocomposite magnets first improve, reach maxima at 1.1 at.% Ga, and then degrade. The addition of Ga helps to control the morphology, especially the grain sizes of both α -Fe and Nd2Fe14B.
