Stability of Bar Code Information Stored in Magnetic Nanowire Arrays

Figure 2

Progressive increase of the fraction of area with up magnetization. The starting point is the rectangle with , namely, the magnetization of all wires in the rectangle pointing down. The left-hand column illustrates the magnetization imposed scheme while the right-hand column gives the energy map with reddish colors marking higher repulsive energy sectors: a palette code is given to the far right. Stars indicate the positions of the wire with the highest repulsive energy.
