Abstract

The magnetization reversal of two configurations of linear magnetic ellipsoidal arrays has been studied by using the micromagnetic simulations. The effect of magnetostatic interaction on the switching field is investigated by altering aspect ratio of ellipsoids while boundary edge spacing is kept fixed. The simulation results showed that, when the field is parallel to the ellipsoid easy axis, the shifted switching field is more than the case when the field is parallel to the ellipsoid hard axis. However, in both configurations the shifted switching field accompany with the more relaxed magnetic pattern.
