A study of the phase structure and magnetic properties of mechanically alloyed and heat-treated Sm_xCo_1-x with x=0.13 to 0.24 has been carried out. Remanence enhancement above 0.5 M_s(M_s=saturation magnetisation) was found in samples with x=0.12 to 0.17 after annealing at 700 °C. A maximum energy product of 16.6 M G Oe was measured for Sm_0.13Co_0.87. Coercive forces above 50 kOe were obtained for x=0.17-0.20 after heat treatment at approximately 800 °C. The highest value of 57 kOe was measured for Sm_0.19Co_0.81.
