The relationship between the phase evolution, nanostructure, exchange coupling, and magnetic properties of Nd[sub 8.4]Fe[sub 86]Mo[sub l.1]B[sub 4.5] magnets prepared by melt spinning (MS) and mechanical milling (MM) are studied by x-ray diffraction, Mössbauer spectroscopy, positron lifetime measurements, high resolution transmission electron microscopy observations, and magnetization measurements. The maximum magnetic energy product (BH)[sub max] for MM magnets annealed at 650 °C or below are notably higher than those of the corresponding MS samples due to the larger amount of the Nd(Fe,Mo)[sub 7] present in the MS samples.
