We propose a simple collective coordinate model, which describes the comprehensive vortex core dynamics, including the resonant behavior, weakly nonlinear regimes, and reversal dynamics. A chaotic dynamics of the vortex polarity is predicted. All analytical results are confirmed by micromagnetic simulations.</p>}, number={6}, journal={Ukrainian Journal of Physics}, author={Pylypovskyi, O. V. and Sheka, D. D. and Kravchuk, V.
