Abstract
NdFeB sintered magnets with the addition of various amounts of FeGa3 powder
were prepared by blending during the ball milling process, The magnetic pr
operties and microstructure of the NdFeB magnets were studied. It was found
that the addition of 0.1-0.2 wt.% FeGa3 powder increases the coercivity of
the magnets without reducing the remanence. The improvement in coercivity
by the addition of FeGa3 powder may be related to the formation of a Nd6Fe1
4-xGax (x congruent to 1) intergranular phase in the magnets.
