利用振动样品磁强计和电子顺磁共振谱仪研究了Fe－Ni／Cu多层膜中的层间耦合和二维效应．以及它们对磁性的影响．对于Fe－Ni（3．0nm）／Cu多层膜，面内饱和场Hs、矫顽力Hc、剩磁比均随Cu层厚度作同步振荡变化．对于Fe－Ni（2．0nm）／Cu和Fe－Ni（3．0nm）／CU多层膜，有效饱和磁化强度与共振线宽△H，随Cu层厚度作同步振荡变化．在它们的铁磁共振谱中，除了一致进动共振模外，还存在着自旋波共振模，进一步证明了上述多层膜中相邻磁层间存在层间耦合．对于Fe－Ni／Cu（2．0nm）多层膜，有效饱和磁化强度随着磁层厚度的增加而增加，而共振线宽△H则随之减小，这些变化是层间耦合和二维效应共同作用的结果．
The interlayer coupling and two-dimensional effect in Fe-Ni / Cu multilayers were investigated by vibrating sample magnetometer and electron paramagnetic resonance spectrometer. And their impact on magnetism. For the Fe-Ni (3.0nm) / Cu multilayers, the in-plane saturation field Hs, the coercive force Hc and remanence ratio all change with the thickness of the Cu layer synchronously. For the Fe-Ni (2.0nm) / Cu and Fe-Ni (3.0nm) / CU multilayers, the effective saturation magnetization and the resonance linewidth ΔH change synchronously with the thickness of the Cu layer. In their ferromagnetic resonance spectra, in addition to the uniform precession resonance modes, spin-wave resonance modes exist, further confirming the existence of interlayer coupling between adjacent magnetic layers in the multilayer films. For Fe-Ni / Cu (2.0nm) multilayer films, the effective saturation magnetization increases with the increase of the thickness of the magnetic layer, while the resonant linewidth △ H decreases. These changes are the interlayer coupling and two-dimensional Effect of the results of the interaction.
