Magnetic skyrmions are nanoscale spin textures with a non-zero topological charge that appear in some condensed matter systems such as magnetic multilayers. About a decade ago it was predicted that they could be transported along a magnetic wire using small electrical currents, and this has led to a variety of proposals for their use in magnetic memory and non-von Neumann computing. However, in practice skyrmion motion is hindered by imperfections in the magnetic material, meaning that far more current is needed than predicted, leading to energy inefficiencies. In this project surface acoustic waves (SAWs) will be used to manipulate skyrmions instead.
