Abstract Radial vortices are exotic magnetic configurations that have several potential applications in Spintronics. In this paper, using micromagnetic simulation, we have proved that magnetic radial vortices can also be found in elliptic nanostructures, and have obtained the frequencies of their spin wave modes as a function of the sizes and ellipticity of the structures (here, we have defined the ellipticity as the ratio of the major axis to the minor axis D = D x / D y ). Our results show that the size of the core of the magnetic radial vortex is not dependent on D. We have also obtained the spatial distribution of Fourier transform power spectra of the spin wave modes. Our results show that the variation in the values of D leads to the emergence of new spin wave modes, and that in general, the increase in the values of D leads to a decrease in the values of the frequencies of the spin wave modes.

具有磁性径向涡旋结构的纳米椭圆的自旋波模式

摘要 径向涡流是奇异的磁性结构，在自旋电子学中具有多种潜在应用。在本文中，使用微磁模拟，我们证明了磁性径向涡流也可以在椭圆纳米结构中发现，并获得了其自旋波模式的频率作为结构尺寸和椭圆度的函数（这里，我们定义了椭圆率作为长轴与短轴的比率 D = D x / D y ）。我们的结果表明，磁径向涡旋核心的大小不依赖于 D。我们还获得了自旋波模式的傅立叶变换功率谱的空间分布。我们的结果表明，D 值的变化导致了新的自旋波模式的出现，一般来说，
