Splitting of Spin Waves in Strain Reconfigurable Magnonic Stripe

We report on the study of the spin wave (SW) propagation in the magnonic waveguide which consists of an irregular magnetic thin film and a piezoelectric layer. We demonstrate that the use of a finite-width piezoelectric layer on the top of a magnetic waveguide leads to controllable SW splitting. By...

Description
Summary:We report on the study of the spin wave (SW) propagation in the magnonic waveguide which consists of an irregular magnetic thin film and a piezoelectric layer. We demonstrate that the use of a finite-width piezoelectric layer on the top of a magnetic waveguide leads to controllable SW splitting. By means of numerical simulation, we demonstrate the functionality of the proposed structure. We show that the switching of SW power is possible due to electric field variation and thus the proposed structure can act as a frequency-selective multichannel SW splitter and multiplexer.
