英文摘要The field-driven magnetization dynamics of a multiskyrmion cluster in a nanodisk is investigated by micromagnetic simulation and analytical calculation. Under a weak in-plane static magnetic field, the multiskyrmion cluster shows an oscillatory motion around an equilibrium position, which resembles the dynamical behavior of the conventional torsional pendulum. We show that this oscillation is induced by restoring torque acting on the skyrmion generated by the potential energy determined by the angle of the skyrmion orientation. Moreover, the multiskyrmion cluster can be driven to rotate by an in-plane rotating magnetic field. The rotation directions and frequencies are fully determined by the number of the skyrmions.
