“…In studies of refs. , different descriptions of the spatial magnetization distribution in the vortex structures were reported. It is worth noting that the use of different types of anzats in the calculation does not affect the qualitative conclusions in describing the vortex structures.…”

The periodic motion of interacting vortex domain walls in a pair of nanostripes has been analytically and numerically investigated. A model consisting of two parallel nanostripes with the domain magnetization structure has been proposed, where domains are separated by vortex walls. The magnetic subsystems of the stripes magnetostatically interact, which causes the existence of normal magnetic vortex motion modes in the latter. Frequencies of the collective magnetization modes have been calculated using empirical expressions for the magnetic energy of interaction between vortex walls. It is shown that not any combinations of the polarity and chirality lead to the resonance magnetization behavior in ac fields.

“…Therefore, to describe the correlation between the magnetizations in the core and at distance r from it, we use the dependence of the perpendicular magnetization component

m_{z}

on the coordinate from ref. :

m_{z} = ξ true(r, δ_{c} true) = \frac{1 - h}{1 + 0.6 \frac{r^{2}}{δ_{c}^{2}}} \exp true(- 0.1 \frac{r^{2}}{δ_{c}^{2}} true) + h

“…The integration is performed on the surface area of the lateral nanodots, as it has been done in the work [10] for the circular nanodots. The results of the numerical integration in the region of small displacements of the core (< a/4, where a is the length of the square) is approximated well by…”

“…(5) is approximate and yields the solution for the gyrotropic motion of the vortex core in the low-frequency (< 1 GHz) range. However, in recent theoretical studies [27][28][29][30] the modified Thiele equation was analyzed with regard to the terms of higherorder derivatives of the coordinate with respet to time:…”
