摘　　要：基于Landau-Lifshitz方程和Maxwell方程组,我们探讨了垂直入射微波在面内单轴各向异性金属磁性三层膜中的传播性质.研究发现由于存在层间交换耦合作用,沿膜厚度方向不均匀的激发磁场显著影响铁磁层的磁导率,导致新颖的微波传播性质.Based upon Landau-Lifshitz equation and Maxwell equations, we investigate properties of normally incident microwave propagation in the exchange coupled trilayer ferromagnetic films with in-plane anisotropy. It is found that, due to existence of interlayer exchange coupling, the inhomogenous exciting magnetic field along film thickness may significengly influence the permeability of the ferromagnetic layers. Subsequently, some novel properties of microwave propagation in the films are expected.
