论文摘要
通过腔fmr研究了两个系列的[RU10/COX）] 12和[RU6/CR3/COX）] 12 x = 16-60个易于平面各向异性各向异性多层（所有厚度），由溅射沉积制备，通过腔FMR研究。通过将垂直于饱和面内场的RF场设置为启用声模式。他们的共振场与磁性测量值的层间交换和各向异性领域相吻合，与宏大模型预测的声音模式预测的值一致。通过设置平行于饱和场的RF场来激发的模式的共振场低于光学模式的预期。根据微磁模拟的结果，这也可以归因于杂交混合模式的存在，这些模拟还表明，模式混合与沿多层厚度沿多层厚度的不均匀磁化曲线有关。
Two series of [Ru10/Cox)]12 and [Ru6/Cr3/Cox)]12 x=16-60 easy-plane anisotropy multilayers (all thicknesses in Å), prepared by sputter deposition, are studied by cavity FMR. The acoustic modes are excited by setting the RF field perpendicular to the saturating in-plane field. Their resonance fields are in good agreement with the values predicted for acoustic modes by macrospin models, using the interlayer RKKY exchange and anisotropy fields derived by the magnetic measurements. The resonance fields of the modes excited by setting the RF field parallel to the saturating field, are lower than those expected for optical modes. This and could attributed to the existence of hybridized mixed modes, according to results of micromagnetic simulations which also show that the mode mixing is related to the inhomogeneous magnetization profile along the multilayer thickness.
