This work explores the frequency comb of magnetic vortex in a square disk and a circular disk created by an out-of-plane and in-plane oscillating field using micromagnetic modeling. The broadest frequency comb ever observed in a magnetic system is displayed. When driven by an out-of-plane field, the robustness of the frequency comb of a vortex in a square disk is significantly enhanced due to a reduction in rotational symmetry when compared to a vortex in a circular disk. In addition, comb lines increase as driven amplitude increases, and frequency spacing could be adjusted in the square disk, so facilitating its application. In a situation where the vortex is driven by in-plane field, the square disk exhibits a significantly neater frequency comb than the circular disk. The conclusion is that magnetic vortex in a square disk is better suited for frequency comb applications.

这项工作利用微磁建模探索了由面外和面内振荡场产生的方盘和圆盘中磁涡旋的频率梳。显示了在磁系统中观察到的最宽的频率梳。当由面外场驱动时，与圆盘中的涡旋相比，由于旋转对称性的降低，方盘中涡旋的频率梳的鲁棒性显着增强。另外，梳状线随着驱动幅度的增加而增加，并且方盘中的频率间隔可以调整，因此有利于其应用。在涡旋由面内场驱动的情况下，方形盘表现出比圆形盘明显更整齐的频率梳。结论是方形圆盘中的磁涡流更适合频率梳应用。
