(a) Depinnig field as a function of for several values of for a CoPtCr strip with and and . Dots correspond to results and lines correspond to the ones obtained from the 1 DM with , , and a pinning potential given by for with and ( for ). (b) Probability of DW depinning () as a function of both () obtained from 1 DM with at . A temporal window of was considered, and stochastic realizations were evaluated. Open dots represent the deterministic () depinning field . (c) Examples of as a function of under three different density currents: (squares), (circles) and (triangles). Filled and open symbols correspond to 1 DM and results respectively (Reprinted with permission From [65]. Copyright (2012), American Institute of Physics).
