Abstract
- The dynamic magnetization switching of a nanostructured exchange-coupled trilayer with a small thickness asymmetry is investigated by micromagnetic simulation. The magnetization switching initially occurs by coherent rotation, followed by magnetization oscillation. The switching time, which is about 9 ns at an applied field just above the switching field, is a factor of two longer than that observed for a single-layered thin film. A Fourier analysis of the magnetization oscillation shows multiple oscillation frequencies, the main frequency of which decreases as the applied magnetic field increases. [ABSTRACT FROM AUTHOR]
