用相干式自旋回波方法观察到Fe4N合金中的57Fe核磁共振谱.各向异性超精细相互作用及畴壁位移激发造成了FeⅡ的奇异核磁共振线形.The nuclear magnetic resonance spectrum of 57Fe nuclei in γ - Fe4N alloy has been observed by the coherent spin-echo method. The peculiar line shape of nuclear magnetic resonance of Fe Ⅱ arises from the anisotropic hyperfine interactions and the domain wall excitation.
