Skyrmion Dynamics in Multiferroic Insulator
arXiv:1209.3120 · doi:10.1103/PhysRevB.87.100402
Abstract
Recent discovery of Skyrmion crystal phase in insulating multiferroic compound CuOSeO calls for new ways and ideas to manipulate the Skyrmions in the absence of spin transfer torque from the conduction electrons. It is shown here that the position-dependent electric field, pointed along the direction of the average induced dipole moment of the Skyrmion, can induce the Hall motion of Skyrmion with its velocity orthogonal to the field gradient. Finite Gilbert damping produces longitudinal motion. We find a rich variety of resonance modes excited by a.c. electric field.
