对于一个复合多铁性链对应的BaTiO 3/Fe界面，我们报告的铁磁共振依赖于耦合的Landau-Khalatnikov方程的FE极化和Landau-Lifshitz-吉尔伯特方程的磁化运动的解决方案的光谱的理论计算。我们关注系统大小的作用。此外，我们发现，虽然磁电耦合强度保持线性的电场变化，其依赖于铁磁体的厚度不是线性的。
For a composite multiferroic chain corresponding to a BaTiO3 /Fe-interface we report theoretical calculations of the spectra of ferromagnetic resonance relying on the solution of the coupled Landau-Khalatnikov equation for the FE polarization and the Landau-Lifshitz-Gilbert equation for the magnetization motion. We focus on the role of the system size. Additionally, we find that although the magnetoelectric coupling strength remains linear upon the electric field variation, its dependence on the thickness of the ferromagnet is not linear.
