Control of topological magnetic textures has attracted intense interest due to the potential applications for these structures in spintronic devices. Recent advances in electron microscopy have enabled imaging of individual skyrmions, however the full understanding of their ultrafast dynamics has remained inaccessible. Here we show via cryoLorentz microscopy that a single circularly polarized femtosecond laser pulse can induce controlled rotation of a skyrmion crystal. Pulses of light with an…

Ultrafast non-thermal control of magnetization by instantaneous photomagnetic pulses
TLDR
It is demonstrated that circularly polarized femtosecond laser pulses can be used to non-thermally excite and coherently control the spin dynamics in magnets by way of the inverse Faraday effect, and offers prospects for applications of ultrafast lasers in magnetic devices.

Thermally driven ratchet motion of a skyrmion microcrystal and topological magnon Hall effect.
TLDR
The finding that a topologically nontrivial spin texture known as a skyrmion--a particle-like object in which spins point in all directions to wrap a sphere--constitutes such a ratchet is reported, suggesting that magnons can be used to control the motion of these spin textures.

TLDR
Topological quantization, high mobility, and the confinement of Skyrmions in channels provided by the helical background may be useful for future spintronics devices.

TLDR
It is shown that in an inhomogeneous temperature gradient caused by illumination in a Lorentz transmission electron microscope different parts of the Skyrmion lattice can be set into motion with different angular velocities.
