Despite the high theoretical energy product and low material cost of Fe-rich 2:17-type Sm-Co-Fe-Cu-Zr magnets,it is still a big challenge to simultaneously achieve high energy product and high coercivity due to damage...

Influence of Zr contents on high-temperature magnetic performance of Sm(CoFeCuZr)(x=0.025,0.03,0.035,0.04) magnets were investigated.As x increases from 0.025 to 0.04,the temperature coefficient of intrinsic coercivit...
