10-nm-thick γ′-Fe4N films were grown epitaxially on LaAlO_3(001) and MgO(001) substrates by molecular beam epitaxy using solid Fe and a radio-frequency NH_3 plasma. The lattice mismatch of these substrates to γ′-Fe_4N is 0% and 11%, respectively. Spin and orbital magnetic moments of these γ′-Fe_4N epitaxial films were deduced by x-ray magnetic circular dichroism measurements at 300 K. The total magnetic moments are almost the same for the two substrates, that is, 2.44±0.06 μ_B and 2.47±0.06 μ_B, respectively. These values are very close to those predicted theoretically, and distinctively larger than that for α-Fe.
