通过测量300K~420K温度范围内的磁导率谱，系统研究了倾斜沉积技术生长的FeCoHf薄膜的温度依赖性动态磁化强度。随着倾斜角从27°变化到45°，300K时谐振频率从2.4GHz增加到3.8GHz。高倾斜角样品的热稳定性不如低倾斜角样品。此外，还详细讨论了不同倾斜角度下有效吉尔伯特阻尼因子、频率线宽以及静态和动态磁导率随温度的变化。 (C) 2012 年美国物理研究所。 [http://dx.doi.org/10.1063/1.4763361]
Temperature-dependent dynamic magnetization of FeCoHf thin films grown by oblique deposition technique was investigated systematically through the measurement of permeability spectra in a temperature range from 300K to 420 K. With the change of oblique angle from 27 degrees to 45 degrees, the resonance frequency is increased from 2.4 GHz to 3.8 GHz at 300 K. The thermal stability for the samples with high oblique angle is not as good as that of the ones with lower oblique angle. In addition, the variation of the effective Gilbert damping factor, frequency linewidth, and static and dynamic permeabilities with temperature for different oblique angles are presented and discussed in detail.
