Abstract :
Magnetization dynamics of submicron elongated Pac-man (EPM) shaped Ni80Fe20 thin film elements were studied using micromagnetic simulation. In-plane magnetic field of 390 Oe was applied on the EPM element at a 45deg angle from the long axis. Pulse duration was varied to reduce magnetization ringing. From information on the contributions of the shape anisotropy, applied field, and demagnetization energy in the magnetization reversal including magnetization ringing, it was found that pulse adjustment controls the magnetization process of the EPM element and the switching pulse duration is an important parameter to design magnetic random access memory (MRAM) device
