Abstract: Spark plasma sintering method is used for studying the structure and magnetic properties for Sm[([Co.sub.0.74][Cu.sub.0.12][Fe.sub.0.1][Zr.sub.0.04]).sub.7.6] nanocrystalline ball milled powders and bulk magnet. The coercivity of the powders has decreased as the annealed temperature has increased and the Mr/Mn ratio of 0.63 has shown the existence of intergrain exchange coupling among the nanograins.
