对电沉积Ｎｉ－Ｆｅ合金的穆斯堡尔谱分析表明γ相Ｎｉ－Ｆｅ合金的同质异能移（Ｉ．Ｓ．）为－０．０６～０．０２ｍｍ／ｓ；α相的Ｉ．Ｓ为～＋０．０５ｍｍ／ｓ，与冶炼Ｎｉ－Ｆｅ合金的Ｉ．Ｓ．（冶炼Ｎｉ－Ｆｅ合金的γ相Ｉ．Ｓ为－０．１９～－０．２２ｍｍ／ｓ；α相Ｉ．Ｓ．为－０．０７～０．１０ｍｍ／ｓ）相比，向正值方向偏移，γ相平均偏移０．１８ｍｍ／ｓ，α相约０．１３ｍｍ／ｓ．电沉积Ｎｉ－Ｆｅ合金的磁超精细场随合金中Ｆｅ含量的变化情况与冶炼Ｎｉ－Ｆｅ合金中的情况不完全一样。此外，还观察到电四极裂矩不等于零，表明电沉积Ｎｉ－Ｆｅ合金中存在电场梯度．根据镀层合有杂质Ｓ和结构缺陷的特点，讨论了上述穆斯堡尔参数的变化情况。
Mossbauer spectroscopy analysis of electrodeposited Ni-Fe alloy showed that the I.S. of γ-phase Ni-Fe alloy was -0.06 ~ 0.02mm / s; S is ~ + 0.05mm / s, and smelting Ni-Fe alloy I. S. (Γ-phase I.S of the smelting Ni-Fe alloy is -0.19 to -0.22 mm / s; α-phase I.S. is -0.07 to 0.10 mm / s) Offset, the average γ phase shift 0.18mm / s, α phase about 0.13mm / s. Electrodeposition of Ni-Fe alloy magnetic hyperfine field changes with the alloy Fe content and smelting Ni-Fe alloy is not exactly the same. In addition, it is also observed that the electrical quadrupole moment is not equal to zero, indicating that there is an electric field gradient in the electrodeposited Ni-Fe alloy. According to the characteristics of the coating with impurities S and structural defects, the changes of the above Mössbauer parameters are discussed.
