Nanoscale spin waves get excited

Nature Physics volume 19, pages 469–470 (2023)Cite this article

Subjects

Disturbances in the orientation of magnetization in a magnet can propagate as spin waves or magnons. A design that makes it possible to optically excite nanoscale spin waves offers a route to developing miniaturized spin-based devices.
