Magnetic nano-skyrmions are expected to act as data carriers in the magnetic memories of the future, and research is currently being carried out to create and transport skyrmions in thin magnetic films.
A team of researchers led by Professor Johan Åkerman at the Department of Physics has now shown in a new study that skyrmions can be stabilised using a new method and transported in the usual way, i.e. in a stream that is led through the magnetic material.
“Since there is an insatiable appetite for storing information, such as mobile phones, computers and especially online, nano-skyrmions have great potential as data carriers,” explains Professor Åkerman. “They can be made extremely small and are easy to program with spin-polarised streams, for example in MRAM.”
