Abstract

We investigate effect of a point defect on the pinning potential for a perpendicular magnetic domain wall based on the NEB method. We find that this method can give a reasonable value for the pinning potential and allows us to study the effect of various geometrical and magnetic properties on the pinning potential. In the presentation, we will discuss the effect of Ku and wire width on the pinning potential in detail.
