  Magnetic skyrmions are chiral quasiparticles that show promise for future
spintronic applications such as skyrmion racetrack memories and logic devices
because of their topological stability, small size (typically $\sim3-500$ nm),
and ultralow threshold force to drive their motion. On the other hand, the
ability of light to carry and deliver orbital angular momentum (OAM) in the
form of optical vortices has attracted a lot of interest. In this work, we
predict a photonic OAM transfer effect, by studying the dynamics of magnetic
skyrmions subject to Laguerre-Gaussian optical vortices, which manifests a
rotational motion of the skyrmionic quasiparticle around the beam axis. The
topological charge of the optical vortex determines both the magnitude and the
handedness of the rotation velocity of skyrmions. In our proposal, the twisted
light beam acts as an optical tweezer to enable us displacing skyrmions over
large-scale defects in magnetic films to avoid being captured.
