Magnetic spin waves brought under control to enable nanocircuits

As demand for more intelligent devices increases, so does the need to squeeze ever more processing power into smaller and smaller microchips.
The spin wave remains trapped in the domain wall, which is formed in the middle between the differently oriented magnetizations. Researchers at the HZDR could thus control its propagation purposefully. (© HZDR/H.
