Single-Pulse Optical Switching combined with Current-Induced Motion of Skyrmionic Spin Textures
The research demonstrates a new method to control magnetic skyrmions using both light and electricity. A single 30 fs laser pulse can deterministically flip the core polarity of a skyrmion while simultaneously allowing it to move across a patterned wire structure driven by spin-orbit torques. This combines optical control over the internal state with electrical control over spatial position.
