a1 XRD patterns of SFNM+\(x\)Fe (x = 0.0, 0.5, 0.8, 1.2) reduced at 800 °C for 2 h in 5% H2/N2 from 20 to 80°. Amplified XRD patterns in the range of a2 41–45° and a3 31.5–33°. b1 XRD patterns of re-oxidized SFNM+\(x\)Fe-red at 1000 °C in air for 10 h. Amplified XRD patterns in the range of b2 35–45° and b3 26–31°.
