中文摘要：

以便完成容易的制造和可观的方向性的取向，我们使用一个沉积方法准备由 FeSiAl 薄片组成的 composites。薄片在 hydroxylated 被驱散在进把压成薄片的合成样品的 sonication 和自然形式的丙烯酸的树脂答案。然后， toroidal 戒指与准备把压成薄片的合成样品被做。与随机的 orientational FeSiAl 薄片在相比合成，当微波频率在 4 GHz 下面时，把压成薄片的样品的复杂渗透显然被改进了，特别为想象的部分。一个模型被建议解释由这个方法合成的排列 FeSiAl 的形成原因。抑制因素() 被有效中等理论和 Landau-Lifshitz-Gilbert 方程的联合计算，并且样品的渗透被这些理论验证。

英文摘要：

In order to achieve an easy fabrication and considerable directional orientation, we use a sedimentation method to prepare composites consisting of Fe Si Al flakes. The flakes are dispersed in hydroxylated acrylic resin solution in sonication and natural form into laminated composite samples. Then, the toroidal rings are made with the prepared laminated composite samples. Compared with random orientational Fe Si Al flakes in the composite, the complex permeability of laminated sample has been obviously improved when microwave frequency is below 4 GHz, especially for the imaginary part. A model is proposed to explain the formation reason of aligned Fe Si Al composite by this method. Damping factor（α） is calculated by the combination of the effective medium theory and Landau-Lifshitz-Gilbert equation, and the permeability of the samples is verified by these theories.
