《FeGaB(25 nm)/Al_2O_3/FeGaB(25 nm)多层薄膜结构:氧化铝(Al_2O_3)厚度变化对静态与动态磁性能的影响（英文）》
Complex permeability spectrum was measured for the multilayer films where well defined uniaxial anisotropy was developed[36].Figs.6a~6f present the experimentally measured permeability spectra in zero bias field for the samples grown with different thicknesses of Al2O3 in the frequency range from 0.5 GHz to 4.0 GHz.Strong ferromagnetic resonance characteristics are observed.The resonance frequency floats around 1.55 GHz and has weak dependence on the oxide layer thickness.These values are very close to the calculated resonance frequency fr，cal using Ms and Hk，as listed in Table 1.The real and imaginary permeability values decrease and the width of the imaginary permeability peak increases as the oxide layer gets thicker.Generally the existences of inhomogeneous domain orientation and damping are indicated[37，38].To quantitatively understand the effect of insulating layer onto the dynamic magnetic properties of the multilayer films，the complex permeability spectrum was further analyzed based on the Landu-Lifchitz-Gilbert（LLG）model that phenomenologically explains the dynamic magnetization behavior of magnetic materials[39]by the equation:
