Abstract

This study reports micromagnetic simulations of the dynamics of standing spin waves in microstructured hard-soft bilayers. It is found that the standing spin wave resonance property can be continuously varied with layer thickness ratio. Numerical results demonstrate feasibility of the microstructured hard-soft bilayer strips for the integrated spin wave devices, where the thickness ratio of the exchange coupled hard-soft bilayer can be a structural design parameter.
