Magnon transistor for all-magnon data processing

An attractive direction in next-generation information processing is the development of systems employing particles or quasiparticles other than electrons—ideally with low dissipation—as information carriers. One such candidate is the magnon: the quasiparticle associated with the eigen-excitations of magnetic materials known as spin waves. The realization of single-chip all-magnon information systems demands the development of circuits in which magnon currents can be manipulated by magnons themselves. Using a magnonic crystal—an artificial magnetic material—to enhance nonlinear magnon–magnon interactions, we have succeeded in the realization of magnon-by-magnon control, and the development of a magnon transistor. We present a proof of concept three-terminal device fabricated from an electrically insulating magnetic material. We demonstrate that the density of magnons flowing from the transistor’s source to its drain can be decreased three orders of magnitude by the injection of magnons into the transistor’s gate.

“…При этом вызванные развитием параметрической неустойчивости вклады в дисперсию ∆k ′ и пространственный декремент ∆k ′′ ПМСВ определяются не только уровнем надкритичности C, но также расстоянием L, которое пробежала волна. В случае 3М процессов нелинейные добавки при надкритичностях C > 0 дБ могут составить ∆k ′ ∼ ∆k ′′ ≈ 30-50 см −1 , тогда как в случае 4М распадов имеем ∆k ′ ∼ ∆k ′′ ≈ ≈ 2-4 см −1 [23]. С другой стороны, величина изменения дисперсии на частоте дефектной моды составляет ∆k DM ≈ 5 см −1 [12].…”

“…2, в при надкритичности C ≈ 9-26 дБ, величина ∆T DM существенно уменьшается. При C ≥ 26 дБ в результате роста нелинейного затухания[23,24] 3М процессы приводят к понижению величины ∆T DM до уровня ∆R DM ≈ 6 дБ. При C ≈ 6 дБ изменение ∆R DM ≈ 3.7 дБ, а при C ≈ 9 дБ не превышает ∆R DM ≈ 0.7 дБ.…”

“…При надкритичности C > 11 дБ величина ∆R можно показать, что на частоте f DM действительно имеет место эффект усиления амплитуды поля волны. Для этого мощность ПМСВ P sw свяжем с амплитудой СВЧ намагниченности m спиновой волны с помощью выражения[23]…”

An induced nonlinear phase shift of spin waves excited in an yttrium iron garnet film waveguide has been studied. Experiments were performed with two microwave magnonic signals, being operating and pumping waves, co-propagated at different frequencies. The results show that a nonlinear phase shift up to 180° for the low-power operating wave is induced when increasing the pump-wave power. A theory describing the induced nonlinear phase shift is developed taking into account four-wave parametric coupling and nonlinear damping of two waves. The observed phenomenon paves the way to elaborate different types of nonlinear magnonic logic circuits.
