Abstract

The effects of thickness asymmetry (Δt) on the dynamic magnetization switching of exchange-coupled trilayers are investigated in this study. Elliptical thin films that have lateral dimensions of 200×100 nm ² are considered. A significant difference in the dynamic switching behavior is observed depending on Δt. Both the switching field and the switching time decrease as Δt increases. A Fourier analysis of the magnetization oscillation, which is followed by the initial coherent rotation, shows multiple oscillation frequencies. This tendency is more pronounced at a larger Δt. The main oscillation frequency tends to increase with an increase in Δt.
