All magnets — from the simple souvenirs hanging on your refrigerator to the discs that give your computer memory to the powerful versions used in research labs — contain spinning quasiparticles called magnons. The direction one magnon spins can influence that of its neighbor, which affects the spin of its neighbor, and so on, yielding ...
An international team from Delft, Lancaster, Nijmegen, Kyiv, and Salerno has demonstrated a new technique to generate spin waves that propagate through the material at a speed much faster than the speed of sound. These so-called spin waves produce a lot less heat than conventional electric currents, making them promising candidates for future computation devices ...
