23. The theory lines in Figs. 4(a) and 4(b) were obtained by fitting the theory to the simulation results using one adjustable scaling parameter C that is a multiplier for the R/D scale. C depends on the relationship between the disk magnetic moment and the core position, which depends weakly on geometry. Using fits to the core displacement vs. Ms from single vortex simulations, we estimate that a scaled value of C = 2.51 should be used in the theory described in Ref. 21 to obtain f/f0 for the experimental geometry. The change in f/f0 due to this correction is ≤2% for R/D = 0.44.

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.
