Scientists see spins in a 2D magnet

All magnets—from the simple souvenirs hanging on your refrigerator to the disks 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 what are known as spin waves. Information can potentially be transmitted via spin waves more efficiently than with electricity, and magnons can serve as “quantum interconnects” that “glue” quantum bits together into powerful computers.
