New method for using spin waves in magnetic materials

High-frequency magnetic waves, by contrast, can propagate in even the smallest nanostructures and thus transmit and process information. The physical basis for this is the so-called spin of electrons in the magnetic material, which can be simplified as a rotation of the electron around its own axis. However, spin waves in microelectronics have so far only been of limited use, due to the so-called damping, which acts on the spin waves and weakens them.
Physicists at the University of Münster (Germany) have now developed a new approach that eliminates unwanted damping and makes it easier to use spin waves. "Our results show a new way for the application of efficient spin-driven components," says Dr. Vladislav Demidov, the head of the study (Institute for Applied Physics, Research Group Demokritov). The new approach may be relevant for future developments in microelectronics, but also for further research into quantum technologies and novel computer processes. The study was published in the journal "Nature Communications."
