FIG. 1.

Schematic description of the H-bar geometry used in the simulation. The magnetic easy axis is along the two legs of the H, and the crossbar at the center represents the constriction. The thick arrows show the local magnetization orientation.

FIG. 2.

Different types of domain walls obtained during the simulations. (a) Bloch wall, (b) Néel wall, and (c) vortex wall. All the images are .

FIG. 3.

Energy diagram of the different types of domain walls for . Symbols are simulated data and the lines are the linear fits.

Image of FIG. 4.
FIG. 4.

Crossbar size-dependent Néel wall width. Symbols are obtained from the simulations. The lines are the fittings utilizing formula (1) shown below. The inserted figure shows the typical domain wall profile; symbols are simulated data, and the line is the fitting with the formula .
