(a) Sketch of the T-structures used in the experiment. (b) XMCD image of a thick permalloy sample with and . The arrows indicate the magnetization direction, the inset shows the line scan across the domain wall. (c) Enlarged view of the line scan. (d) Magnetization distribution calculated with OOMMF for a comparable element.
Example of a domain wall evaluation: The experimental data (squares) is compared to a Boltzmann function (line). Its derivative (dashed line) is then fitted by a Gauss function (dotted line) and we define the core wall width as its full width at half maximum.
Dependence of the core domain wall width on the contact size for permalloy T-structures with a cross-beam width of (a) and (b) . The filled squares show the experimental data measured with XPEEM, the hollow circles are values calculated with OOMMF.
