Figure 7: Cross-sectional ( ) averages for total, stray field, and exchange energy densities as a function of the location along the wall for the simulation in Figure 6, and the energy density for a Néel wall in the same geometry. The center of the vortex core is in the cross-section at offset , and the center of the cross-tie core is at . The two half-width dashed red lines indicate the average energy density of the cross-tie/vortex wall across each corresponding half-period.
