Abstract We present three-dimensional (3D) model of periodic meander-shaped ferromagnetic films. Spin wave propagation in such films and vertically coupled structures was studied using micromagnetic modeling and theoretical plane wave method. Spin waves in these structures essentially propagate in film’s segments located at right angles with respect to each other. This makes really possible for the wave to propagate in three dimensions. We calculated internal effective magnetic fields and obtained spin wave dispersion in single and vertically coupled structures. Additionally, comparison of surface and volume spin waves propagation in such meander films was provided. Our results can be useful for magnonic logic elements development.

三维磁子晶体和耦合结构中的自旋波传播

摘要 我们提出了周期性曲折形铁磁薄膜的三维 (3D) 模型。使用微磁建模和理论平面波方法研究了这种薄膜和垂直耦合结构中的自旋波传播。这些结构中的自旋波基本上在彼此成直角的薄膜段中传播。这使得波在三个维度上传播真正成为可能。我们计算了内部有效磁场并获得了单个和垂直耦合结构中的自旋波色散。此外，还提供了这种曲折薄膜中表面和体积自旋波传播的比较。我们的结果可用于磁逻辑元件的开发。
