A series of SmTiFe₁₁-_xCo_x compounds where x ranges from zero to five, have been studied by ⁵⁷Fe Mössbauer spectroscopy, X-ray diffraction and related magnetic measurements. The radom site occupation of Co atom in SmTiFe₁₁-xCox was found when x ≥ 1. The temperature dependence of the magnetic hyperfine field for SmTiFe₁₁ and the Co concentration dependence of the magnetic hyperfine field for the samples, SmTiFe₁₁-xCox are obtained. Also the Debye temperature of SmTiFe₁₁ have been estimated from the experiments.
