Abstract:Magnetic skyrmion-based spin-torque nano-oscillators (STNOs) have attracted significant interest because of their potential applications as microwave signal emitters and integrability in the existing CMOS process flow. However, the stable circular motion of the skyrmion in the nanodisk is affected by the Magnus force, which can destroy and annihilate the skyrmion at the nanodisk edge, thereby limiting the application of the maximum oscillation frequency. To overcome this problem, we investigated the influence … Show more
