(a) Equilibrium state of the Bloch wall. (b) Magnetization profile averaged over the strip width .
Averaged DW velocity along a perfect strip under static fields (a) and dc (b). Dots correspond to results; while lines were computed from the 1DM with and .
Equilibrium states at (a) 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 line is the fitting to , where .
(a) Depinning field as a function of for several values of . Dots correspond to results and lines correspond to the ones obtained from 1DM. (b) Dependence of on as deduced from the 1DM analysis of the DW depinning (dots). Red solid line is the fit to with and .
(a) Probability of DW depinning as a function of both obtained from 1DM with at . A temporal window of was considered, and 100 stochastic realizations were evaluated. Open dots represent the deterministic depinning field . (b) Examples of as a function of under three different density currents: (squares), (circles), and (triangles). Filled and open symbols correspond to 1DM and results, respectively.
