Skyrmion lattice dynamics — •Lukas Heinen and Achim Rosch — Institute for Theoretical Physics, University of Cologne, Germany

Chiral magnets host a rich magnetic phase diagram, of which the skyrmion lattice phase is particularly interesting. Skyrmions carry an integer winding number and hence are topologically protected. In addition, making them a promising candidate for future spintronic devices, they are easy to manipulate. Early on it was demonstrated that even the small temperature gradient induced by a Lorentz Transmission Electron Microscope is enough to induce a rotation in a skyrmion lattice. We examine the dynamics of such a rotating skyrmion lattice, by combining micromagnetic simulations with point particle simulations. Of particular interest is the role of defects in the skyrmion lattice.
