Fe-simulation of fast switching behavior of granular nanoelements

Summary form only given. Magnetic switching of mesoscopic and nanostructured thin film elements becomes increasingly important in magnetic storage, microsensors and magneto electronic devices. The switching fields and times which are in the order of pico- to nanoseconds are controlled by the choice of the geometric shape and microstructure of the nanomagnets, the intrinsic properties and the orientation and strength of the applied field. Detailed distribution of the magnetization inside the nanoelements is obtained through numerical integration of the Landau-Lifshitz Gilbert equation of motion. The present study is the first micromagnetic simulation taking into account the granular microstructure of the films.
