Title: Effect of FeGa{sub 3} powder addition on the magnetic properties of NdFeB sintered magnets

Abstract

NdFeB sintered magnets with the addition of various amounts of FeGa{sub 3} powder were prepared by blending during the ball milling process. The magnetic properties and microstructure of the NdFeB magnets were studied. It was found that the addition of 0.1--0.2 wt.% FeGa{sub 3} powder increases the coercivity of the magnets without reducing the remanence. The improvement in coercivity by the addition of FeGa{sub 3} powder may be related to the formation of a Nd{sub 6}Fe{sub 14{minus}x}Ga{sub x} (x {approx{underscore}equal} 1) intergranular phase in the magnets.
