摘要：

Plasma pressure consolidation (PPC) was used to synthesize exchange coupled composite magnets. The magnets were processed from a mixture of micrometer-size, anisotropic magnetically hard SmCo5 and nanometer size magnetically soft Fe particles. High density magnets were obtained by PPC at the temperature as low as 760 degreesC. The compacted SmCo5/alpha-Fe composite showed single-phase magnetic behavior.
