    • In all simulations we used 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 α=0.006, and the anisotropy was neglected. This corresponds to the exchange length = A/ 4π MS2 ≈5.3 nm, which determines the typical radius of the vortex core. The mesh cells have sizes of 3×3×20 nm.

    • In our simulations the vortex was initially shifted from the disk center on a distance about its core radius. The switching time slightly increases when we place the vortex exactly into the disk center.
