A direct view on spin-waves

February 25, 2016
Spin-waves are promising candidates for future information processing schemes as there is almost no frictional heating in magnetic transport. Information encoding, however, is only possible in spin-wave packets. A group of Hamburg-based CUI researchers has succeeded in creating and capturing such defined wave-packets in slow-motion videos. The team describes its experimental set-up for uncovering the ultrafast processes in the interdisciplinary journal Scientific Reports. In addition, the experiment generated a wave-motion which approaches the excitation region from a distance rather than emerging out of it. The motion contradicts human intuition similar to a “moonwalk”. [more]
