使用自旋波共振测量了多种铁镍合金的铁磁交换常数，其成分范围为 60% 至 90% 镍。交换常数从值 1.3 (10-6) erg 平滑变化。 60% Ni 时的 cm-1 至 100% Ni 时的外推值 0.77 (10-6)。这些数据与鲁索夫公布的数值存在显着差异。
The ferromagnetic exchange constant has been measured using spin wave resonance in a number of iron-nickel alloys covering the composition range 60% to 90% nickel. The exchange constant varies smoothly from a value of 1.3 (10-6) erg . cm-1at 60% Ni to an extrapolated value of 0.77 (10-6) at 100% Ni. The data are in significant disagreement with the values published by Rusov.
