Title: Tuning Edge Localized Spin Waves in Magnetic Microstripes by Proximate Magnetic Structures.

Abstract

The propagation of edge localized spin waves (E-SWs) in yttrium iron garnet (YIG; Y3Fe5O12) microstripes with and without magnetic microstructures in close proximity is investigated by micromagnetic simulations. A splitting of the dispersion curve with the presence of permalloy (Py; Ni81Fe19) stripe is observed. The results show that E-SWs on the two edges of YIG stripe have different wavelengths, group velocities, and decay lengths at the same frequencies. The role of the Py stripe was found to be the source of the inhomogeneous static dipolar field without dynamic coupling with YIG. This work opens new perspectives for the design of innovative spin wave interference-based logic devices.
