9. We used for all OOMMF simulations material parameters adopted for the Py particle: the exchange constant A=2.6× 10-6 erg/cm, the saturation magnetization MS =8.6× 102 G, the damping coefficient η=0.006, and the anisotropy was neglected. This corresponds to the exchange length a= A/4π MS2 5.3nm. The mesh cells have sizes 3×3×hnm, where h is the thickness of the sample. The applied field was used in form b (t) =b (1- e- t2 /Δ t2) (cosωt,sinωt,0), with Δt=50ps.

13. The cells with fixed magnetization contribute to the effective field but they are omitted from the procedure of numerical time integration of the LL equation.
14. For the planar vortex the magnon modes with opposite m are degenerated; for the general case see, e.g., Ref..
