Direct-current-gated coherent-magnon transistors
Precise control and utilizing the phase degree of freedom of spin waves is particularly crucial in developing unparalleled magnonic devices for unconventional computing. By exploring phases of coherent spin waves, we have achieved their constructive (destructive) interference, resulting in complete transmission (suppression) of spin-wave propagation in a wide frequency range. Furthermore, by applying a dc-gating current, we effectively switch types of the interference from constructive to destructive or vice versa at the same frequency, enabling the configurable realization of both xor and or logic functions in the same device. Our coherent spin-wave transistor gateable by a dc current represents a substantial step forward to the spin-wave logic devices or circuits for magnonic computing.
