WebThe transistor is based on a magnonic crystal designed in the form of an yttrium iron gar- net (YIG) film with an array of parallel grooves at its surface. The magnons are injected into the transistor’s source and are detected at the drain using microstrip antennas. WebMar 2, 2024 · The transistor—a device that controls the flow of electrons in a circuit—is the cornerstone of modern electronics. Now three research teams have independently demonstrated equivalent technologies for magnons, magnetic excitations associated with electron spins. These “spin transistors” can directly manipulate a spin current.
Magnon spintronics Nature Physics
The operational principle of the transistor is shown in Fig. 1c. The idea is as follows: magnons are injected into the transistor’s source (S-magnons shown in blue in the scheme in Fig. 1c) at a frequency corresponding to the magnon transmission band, that is, fS=7.025 GHz, see the inset in Fig. 2b. In the case of … See more The magnon transistor is shown schematically in Fig. 1a.
