(a)–(c) 𝑥(𝑡) versus 𝑡 along a rough strip (𝐷_𝑔=3 nm) for different 𝑗_𝑎 with 𝛼_𝑅=10⁻¹¹ eVm at zero (blue-dashed lines) and at room temperature (red-solid lines). (d)–(g) Typical DW configurations under different 𝑗_𝑎. (h) DW velocity as a function of 𝑗_𝑎. (Reprinted with permission From [71]. Copyright (2012), American Institute of Physics).
