The effect of mechanical milling and annealing on the structure and magnetic properties of Sm2Fe14Ga3C2 has been studied. Milling was found to lead to the formation of an amorphous phase. Annealing at temperatures above 700-degrees-C resulted in formation of nanocrystalline SM2Fe14Ga3C2 phase having the Th2Zn17 structure and isotropic magnetic behaviour with coercivities of up to 13 kOe. It has been also shown that anisotropic powders with coercivities of 4-5 kOe can be prepared using low energy milling and subsequent heat treatment.
