Two-dimensional circuit with magnetic quasi-particles

ScienceDaily.com: Nanotechnology News - Mon, 01/22/2018 - 20:11
Whether smart phone, computer or dialysis machine -- there is no electronic device without chips and their electronic components inside. The individual circuit elements are therefore often wired using three dimensional so called bridge constructions. Physicists are now working on a more efficient variation, where specific quasiparticles named magnons instead of electrons are being used. They have shown for the first time, in an initial model, that magnon current flow is possible in an integrated magnon circuit, in which case the components are only being connected two dimensionally.
