In our simulation, permalloy patterns with elliptical and tapered edge need 80% and 50% more switching field, respectively, than a rectangle for the same overall aspect ratio of four. In the switching dynamics, vortex nucleation and its initial location play a great role in deciding switching field. Elliptical and tapered patterns show high magnetic remanence, which is advantageous for non-volatile device application. It is also demonstrated that small control of tapered edge makes it possible to change the switching behavior without the variation of overall aspect ratio.
