Another breakthrough in future magnetic storage devices has been made by JGU and MIT resesarchers. Already in March 2016, the international team investigated structures, which could serve as magnetic shift register or racetrack memory devices. This type of storage promises low access times, high information density, and low energy consumption. Now, the team achieved the billion-fold reproducible motion of special magnetic textures, so-called skyrmions, between different positions, which is exactly the process needed in magnetic shift registers thereby taking a critical step towards the application of skyrmions in devices.

The experiments were ca...
