Magnonic interferometer paves way toward energy-efficient information processing devices

Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. Although magnon signals have discrete phases that normally cannot be changed continuously, the magnonic interferometer can generate a continuous change of the magnon signal. In the future, this ability could be used to design magnonic integrated circuits and other magnonic devices that overcome some of the limitations facing their electronic ...
