利用时间分辨光电电子显微镜研究了平面等边三角形排列中三个磁涡流之间的相互作用。在三盘系统中，三个独立旋涡的旋涡共振频率彼此不同，并且与孤立旋涡的旋涡共振频率相差高达12%。与解析计算和数值模拟的比较表明，观测到的频移是由涡旋之间的偶极相互作用引起的。
The interactions between three magnetic vortices in a planar equilateral triangular arrangement were studied by time-resolved photoemission electron microscopy. The gyrotropic resonance frequencies of the three individual vortices in the tri-disk system are different from one another and also shifted from that of an isolated vortex by as much as 12%. A comparison with analytical calculations and numerical simulations shows that the observed frequency shifts result from the dipolar interaction between the vortices.
