Effects of Doped Element on Structure and Magnetic Performance of Nanocrystalline Sm5Co19 Alloy

摘要

In this study,permanent magnetic nanocrystalline Sm_5Co_(18.5)Ni_(0.5)、Sm_5Co_(18.5)Fe_(0.5) and Sm_5Co_(18.5)Nb_(0.5) alloys with high coercivity were prepared.The microstructure,crystal structure and magnetic properties of these alloys were studied.The results show that Ni,Fe and Nb doping do not lead to phase decomposition of the Ce_5Co_(19) type crystal structure。
