In this study, epitaxial and polycrystalline Fe_4-xCo_xN films with different Co contents were grown on SrTiO₃(001) and Si(001)/SiO₂ substrates, respectively; then λ₁₁₁ and the saturation magnetostriction λ_s were determined experimentally. First-principles calculations of λ₁₁₁ were performed for comparison with the experimental results.
