摘要: Abstract SmCo 5 + x  wt% Fe ( = 0 , and 10) nanocomposite powders were synthesized by mechanical milling consolidated into bulk shape spark plasma sintering (SPS) technique. The evolution of structure magnetic properties systematically investigated in milled as well SPS samples. A maximum coercivity 8.9 kOe was achieved sintered +5 wt% sample. exchange spring interaction between the hard soft phases evaluated using δ M – H measurements analysis revealed that sample containing 5 wt% had a stronger coupling than with10 wt% Fe.
