A joint research project of Johannes Gutenberg University Mainz (JGU) and the Massachusetts Institute of Technology (MIT) that previously demonstrated the use of new spin structures for future magnetic storage devices has achieved yet another milestone. The international team is working on structures that could serve as magnetic shift registers, so-called racetrack memory devices. This type of storage promises low access times, high information density, and low energy consumption. The new insights published in Nature Electronics shed light on the effects of temperature on the dynamics of skyrmions. According to the researchers’ findings, skyrmions move more efficiently at higher temperatures, and their trajectories only depend on the speed of the skyrmions. This makes device design significantly easier.
