    • These simplifications are made, since we are interested in the magnon modes which cause the instabilities, and anisotropy or a larger number of layers, will only cause the appearance of an out-of-plane magnetization at the vortex core.

    • In this paper, it was shown that the effect of multipolar terms is present only for nearest neighbor blocks, and is 17 % of the dipolar interaction. For further neighbors, its effect can safely be neglected.

    • The first-order phase transition is defined strictly for an infinite system. Here, because of the presence of a potential barrier and thus a hysteresis, we have referred to the vortex-HSDF transition as a "first-order" one.

    • The frequency is not strictly zero as there is a very small in-plane anisotropy due to dipole interaction which couples spin to space and breaks spin rotational invariance.
