Magnonic devices can replace electronics without much noise

Electronic devices are getting smaller and will soon hit the limits of performance based on electrical currents. Devices based on magnonic currents would transform the industry, though scientists need to better understand how to control them. Engineers have made an important step toward the development of practical magnonic devices by studying, for the first time, the level of noise associated with propagation of magnon current.
