Damon-eshbach spin waves
WebMagnonics offers a new way for information transport that uses spin waves (SWs) and is free of charge currents. Unlike Damon-Eshbach SWs, the magneto-static forward volume SWs offer the reciprocity configuration suitable for SW logic devices with low power consumption. Here, we study forward volume SW propagation in yttrium iron garnet … WebMar 15, 2024 · Thus, as it follows from the results of simulation, the length of a spin wave for a particular direction in a stripe YIG waveguide can be efficiently manipulated by the external electric field. 4. Conclusion. For the Damon-Eshbach geometry, it is shown, that a nonzero electric field leads to a shift of the minimum of the waveguide modes.
