Potential energy barrier at the bifurcation.
Plot of Zeeman energy needed to move the DW in one of the two branches as a function of Doffset. There is a competition between two potential energy barriers one imposed due to selective trajectory and the other imposed due to geometrical asymmetry. Above 100 nm the potential barrier due to geometrical asymmetry in the PD structure is lower for the DW to move in the upper branch.
