The frequency of the lowest vortex gyrotropic mode vs. dot thickness, ω₀(L) 2p: red squares – the experimental data, blue solid line – the simulated frequencies, green solid line – the calculations according to Eq. (4) accounting vortex mass, black dashed line – calculations without accounting for the vortex mass.
