The NdFe₁₂N_x compound with a ThMn₁₂ structure (space group I4/mmm) was successfully synthesized by nitriding an NdFe₁₂ layer grown on a W underlayer on a single-crystalline MgO(001) substrate. The c-axis expanded from 0.480 to 0.492 nm while the a-axis showed a slight contraction from 0.852 to 0.849 nm after the nitriding. Excellent intrinsic hard magnetic properties of μ₀M_s ∼ 1.66 ± 0.08 T, μ₀H_a ∼ 8 T, and T_c ∼ 550 °C, which are superior to those of Nd₂Fe₁₄B, were obtained.
