Mechanically alloyed Sm-Fe-N magnets with addition of Ga
E. Vasilyeva , D. Januszewski , Marcin Leonowicz
AbstractThe magnetic properties and microstructure of Sm-Fe-N magnets with addition of Ga were studied. It was found that the coercivity initially increased and than decreased when Ga content exceeded 0.5 at\%. Ga substituted Fe in the lattice of Sm2Fe17 phase and formed a (Sm,Ga)-rich phase at grain boundaries. Deterioration of the magnetic properties, for Ga contents above 0.5 at\%, we attribute to a reduced nitrogen solubility in the lattice of the Sm2(Fe,Ga) 17Nx phase and towering of its anisotropy constants
