摘要	The effects of further addition, of carbon on structure and magnetic properties of the Sm20Fe70C10 alloy synthesized by mechanical alloying have been investigated. The main phase is Sm2Fe17Cx or Sm2Fe14C, depending on the composition of starting materials. The Sm2Fe14C phase tends to form when more carbon is added. Remilling and reannealing at a low temperature (600 degrees C) improve the magnetic properties of the alloys. The ratio of remanence to saturation magnetization as high as 0.79 indicates the existence of enhanced exchange coupling between the hard Sm2Fe17Cx and soft Sm2Fe14C/alpha-Fe magnetic phases in the Sm20Fe70C15 alloy.
