Induced nonlinear phase shift of spin waves for magnonic logic circuits

Abstract: 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 non… Show more

“…[12][13][14][15][16] Most of the developed spin-wave Boolean logic gates operate by utilizing the spin-wave phase. [17][18][19][20][21][22] An alternative approach involves encoding data into spin-wave amplitude, 23,24 utilizing constructive and destructive interference patterns. In this scheme, logic "1" or "0" corresponds to maximum and minimum amplitudes, respectively.…”

“…Для перестройки частоты АКР от генератора 8 через сумматор 4 на магнонный кристалл подавался СВЧ-сигнал накачки на некоторой фикси-рованный частоте. Этот сигнал вызывал наведенный нелинейный сдвиг фазы [20] малосигнальной спиновой волны, циркулирующей в АКР. Данный сдвиг фазы приводил к сдвигу резонансных частот АКР.…”

“…Данный сдвиг фазы приводил к сдвигу резонансных частот АКР. Нелинейным механизмом, отвечающим за нелинейный эффект, является четырехволновое параметрическое взаимодействие спиновых волн, как и в работе [20].…”
