The influence of spin-polarized current and the number of magnetic layers on the coupled dynamics of vortices in small-diameter spin-transfer nanooscillators has been studied. Using the software package for micromagnetic modeling SpinPM, the dependence of the frequency on the current magnitude of the currents at which a stationary mode of coupled oscillations of three vortices is observed is found. For the case of three identical magnetic layers, the possibility of implementing different scenarios of coupled vortex dynamics is shown. It was found that numerical calculations for the case of three magnetic layers yield frequencies of stationary coupled oscillations that are lower than those predicted by theory. Built on effective equations for the coordinates of the vortex center.
