Abstract
A micromagnetic simulation of switching behavior in submicron nickel b ars is presented, The bars were discretized into elements 10nm by 10nm by 30nm deep. The switching field and switching mechanism were found to have a strong dependence on the edge roughness of the bars. By incl uding a rough edge, the switching field of the bars was reduced as muc h as 40% and produced agreement with experimental determined values.
