论文摘要
这项工作介绍了铁磁性纳米的微磁模拟，以适用于施加的平面外部磁场的整个方向。当磁场方向在经典的Damon-Eshbach（de）和后卷（BV）几何形状之间逐渐改变时，我们将重点关注磁通模式特征的修改。我们发现，在特定的野外方向上，镁模式参数与经典情况下的参数显着不同，即，模式以复杂的空间分布为特征，并且具有低组速度。该范围的中心对应于外部磁场的方向，这给出了纳米磁化磁化强度的最大非均匀分布。
This work presents micromagnetic simulations in ferromagnetic nanogratings for the full range of directions of an applied in-plane external magnetic field. We focus on the modification of the magnon mode characteristics when the magnetic field orientation is gradually changed between the classical Damon-Eshbach (DE) and backward-volume (BV) geometries. We found that in a specific range of field directions, the magnon mode parameters differ significantly from the parameters in the classical cases, namely, the modes are characterized by complex spatial distributions and have low group velocities. The center of this range corresponds to the direction of the external magnetic field, which gives the maximal nonuniform distribution of the static magnetization in the nanogratings.
