(a) Schematic of the nanostripe with a nucleation pad on the left side and the two configurations [blue (dark), red (bright)] used for the measurements and simulations. (b) Schematic cross section of the nanostripe with the magnetization inside the DW core region for the two configurations and two times . The trapezoid is approximated by an ellipse to evaluate the stray field energy generated by the DW core magnetization. (c) TEM image of a cross section of the GMR nanostripe fabricated using FIB. The inset shows an overview of the cross section.
(a) Velocity (squares) and applied (solid lines) as a function of for both configurations. (b) Single shot measurements for field configurations as specified. For configuration 1 [blue (dark)] the DW is in the precessional regime (thick line), whereas configuration 2 [red (bright)] shows steady state DW movement for almost the same applied fields.
Normalized stray field energy in the edge region as a function of the out-of-plane magnetization angle with as parameter [see Fig. 1(b)].
Micromagnetic simulation of the DW movement for the two configurations specified in Fig. 1 and field values as given.
