FIG. 2.

Interaction energy between two magnetic segments with radius R as a function of the distance S between them.

FIG. 8.

Magnetization reversal of a three-segment wire at different numbers of MC steps. The left (right) magnetic segment is 400 (200) nm long. In this system , normalized with respect to the left segment.

Image of FIG. 9.
FIG. 9.

Magnetization reversal of a three-segment wire at different numbers of MC steps. The left (right) magnetic segment is 10 (22.5) nm in radius. Each magnetic segment is 200 nm long. In this system , normalized with respect to the left segment.
