Spin wave pulses in magnonic bilayers with dispersive coupling
Source abstract
Abstract
A study of peculiarities associated with the propagation of short pulses of surface magnetostatic waves in a yttrium iron garnet (YIG) thin film bilayer is presented from both an experimental and theoretical perspective. A magnetic bilayer structure has been modelled using spatiotemporal coupled mode theory, including a dispersion term for the coupling coefficient. Both the experiment and the theory show that the dispersion of the coupling coefficient plays an important role in shaping the pulse envelope and can result in the splitting of the incident pulse into two pulses. The energy exchange between the ferrite layers can be interrupted when the dispersion of the coefficient is high enough.
