Magnon transistor for all-magnon data processing.

Abstract in brief

• This research explores the use of magnons, which are quasiparticles associated with spin waves in magnetic materials, as potential information carriers for low-dissipation, next-generation data processing systems.
• By utilizing an artificially structured magnetic material called a magnonic crystal, the scientists enhanced nonlinear interactions between magnons, enabling control of magnon currents directly with magnons, leading to the creation of a magnon transistor.
• The proof-of-concept three-terminal device, made from an insulating magnetic material, successfully demonstrated that the flow of magnons could be reduced by a factor of a thousand through magnon injection into the gate, showcasing the potential for magnon-based logic circuits.]
