The dynamics of vortex based spin-torque nano-oscillators is investigatedtheoretically. Starting from a fully analytical model based on the Thieleequation approach, fine-tuned data-driven corrections are carried out to thegyrotropic and damping terms. These adjustments, based on micromagneticsimulation results, allow to quantitatively model the response of suchoscillators to any dc current within the range of the vortex stability. Both,the transient and the steady-state regimes are accurately predicted under theproposed data-driven Thiele equation approach. Furthermore, the computationtime required to solve the dynamics of such system is reduced by about sixorders of magnitude compared to the most powerful micromagnetic simulations.This major breakthrough opens the path for unprecedented high-throughputsimulations of spin-torque vortex oscillators submitted to long-duration inputsignals, for example in neuromorphic computing applications.
