With the rapid advance of miniaturization,data processing using electric currents faces tough challenges, some of which are insurmountable. Magnetic spin waves are a promising alternative for the transfer of information in even more compact chips. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), or as portion of an international research venture,have now succeeded in generating spin waves with extremely short wavelengths in the nanometer range - a key feature for their future application.
