    Abstract

    In this study, the dynamic properties of current-driven RKKY-coupled Skyrmion are analyzed. In particular, the manipulation of Skyrmion oscillation and precession by different RKKY ferromagnetic coupling intensities is explored. The results show that the Skyrmion of the Top and Bottom layers can achieve stable oscillation under certain conditions, and the precession of the Skyrmion presents a circular trajectory. Furthermore, the precession position of the Top layer is ahead of that of the Bottom layer, and the coupling strength changes the difference of the Skyrmion precession radius between the upper and lower layers. In addition, the effects of different driving currents on the dynamic characteristics of Skyrmion are analyzed, and the results show that the driving currents can effectively manipulate the dynamic properties such as the initial oscillation time and stable oscillation radius.
