本文研究了磁性薄膜中的自旋波共振激发现象。在Portis体不均匀(Ⅵ)模型的基础上,提出了非对称体不均匀(AⅥ)模型和表面-体不均匀(s-Ⅵ)模型,很好地解释了实验研究中所观察到的线性自旋波谱,在这些谱中偶奇次模被同时激发,其强度按各自不同的包络线变化。In this work, the phenomena of excitation of SWR (Spin Wave Resonance) in magnetic films are investigated. On the basis of Partis' Volume Inhomogeneity (Ⅵ) Model, the Asymmetric Volume Inhomogeneity (AⅥ) Model and the Surface-Volume Inhomogeneity (S-Ⅵ) Model are proposed. In terms of these models, we can explain satifactorily the linear spectra of SWE, in which the odd and even modes are excited simultaneously with their intensities changing in accordance with different envelopes.
