Skyrmions – nanoscale topologically protected spin textures, are considered as ideal candidates for encoding and transmitting bits of information. This burgeoning research field, however, suffers from the same limitations of all spintronic concepts – the high currents needed to move skyrmions. Magnonics is yet another emerging approach, which main aim is to investigate the behaviour of spin waves in magnetic nanostructures. In essence, spin waves are a propagating re-ordering of the magnetisation and therefore use the least amount of power, making them perfect for driving skyrmions. This project fuses skyrmions with magnonics. The central goal is the formulation of model for the magnon assisted manipulation of skyrmions and their lattices.Read moreRead less
