Static Properties and Current-Driven Dynamics of Domain Walls in Perpendicular Magnetocrystalline Anisotropy Nanostrips with Rectangular Cross-Section
Figure 7
(a) Scheme of a pinning site consisting on two rectangular notches at both edges of the strip. (b) Equilibrium state of a pinned DW in a CoPtCr strip of with a constriction described by and . (c) Equilibrium DW position as a function of the applied field in the pinned regime. (d) Pinning potential as a function of the DW position. Dots correspond to micromagnetic results and the solid lines are the fittings to . In these last graphs the length of the notch is fixed to , and three different widths are evaluated: .
