Average DW velocity versus (a) applied magnetic field and (b) normalized current. (c) Dependence of DW velocity at the Walker breakdown (field-driven case) and critical current for steady DW motion (current-driven case) on PMA.

FIG. 3.

(a) DW position as a function of time at , which is less than . The and curves saturate at about 170 nm and 180 nm, respectively, after 25 ns. (b) DW displacement as a function of current below . (c) Dependence of DW adiabatic displacement efficiency on PMA. Data for a wider strip are shown as well for reference.
