| 摘 要： | 为获得具有较高复磁导率虚部的磁性材料并研究其微波物性，采用磁控溅射方法，制备Fe1-xBx磁性纳米膜，以Landau-Lifshitz-Gibert方程研究复磁导率虚部随纳米膜各向异性场、饱和磁化强度和阻尼系数的变化规律，采用谐振腔法开展点频测试。结果表明，测试数据与理论计算值吻合较好。结合Fe1-xBx样品的制备，分析了其磁导率虚部随制备工艺、组分、厚度等的变化规律，这对于获得高磁导率（虚部）的磁性纳米膜具有指导意义。

| Abstract: | The Fe1-xBx ferromagnetic nanofilms have been fabricated by rf sputtering. The relationship between permeability and saturation magnetization, magnetic anisotropy field and damping factor was investigated by using Landau-Lifshitz-Gibert equation. The experimental data obtained by point-frequency measurement at 2 GHz were in agreement with that by theoretical calculation. The relationship between the permeability image of nanofilms and fabrication technics, film composition and thickness was also discussed. |
