Skyrmion Lattices in Random and Ordered Potential Landscapes
Charles Reichhardt
Abstract
Since the initial discovery of skyrmion lattices in chiral magnets 1 there has been a tremendous growth in this field as an increasing number of compounds are found to have extended regions of stable skyrmion lattices 2 even close to room temperature 3 These systems have significant promise for applications due to their size scale and the low currents or drives needed to move the skyrmions 4 Another interesting aspect of skyrmions is that the equations of motion h
