  Electric control of magnetic vortex dynamics in a reproducible way and on an
ultrafast time scale is key element in the quest for efficient spintronic
devices with low-energy consumption. To be useful the control scheme should
ideally be swift, scalable, non-invasive, and resulting in reliable magnetic
switching. Such requirements and in particular the reproducibility of altering
the vortex chirality and/or polarity are not yet met by magnetic vortex
switching via external magnetic fields, spin-polarized currents, spin waves, or
laser pulses. Here we demonstrate a novel packaged-skyrmion mediated vortex
switching process driven by a simple sequence of picosecond electrical field
pulses via magneto-electric interactions. Both the vortex chirality and
polarity show a well-defined reversal behaviour. The unambiguously repeated
switching between four different magnetic vortex states provides an
energy-efficient, highly localized and coherent control method for non-volatile
magnetic vortex-based information storage and handling.
