We have grown Sm(Fe_1 − xCo_x)₁₂ (x = 0, 0.1 and 0.2) films epitaxially on V(001) buffered MgO(001) single crystalline substrates in order to investigate the intrinsic hard magnetic properties of the Co substituted SmFe₁₂ phase with the ThMn₁₂ structure. We found Sm(Fe_0.8Co_0.2)₁₂ has excellent intrinsic hard magnetic properties with spontaneous magnetization of 1.78 T, anisotropy field of 12 T and Curie temperature of 859 K, all of which are superior to those for Nd₂Fe₁₄B. Hence, the Sm(Fe_0.8Co_0.2)₁₂ compound is promising as permanent magnet material, if it can be stabilized in a bulk form.
