FIG. 1.

(a) Typical device used for all measurements (see text). (b)–(d) Schematic illustrations of the used layers stacks, the different Pt/Co interface qualities depending on the bottom Pt layer thickness and calculated current-density distributions in the stacks.

FIG. 2.

Average DW velocity of 20 measurements plotted as a function of applied field for (J = 0, ±3.4 × 1011, ±5.1 × 1011 A/m2), the error bars indicate the standard deviation. Results obtained in: (a) Pt4/Co/Pt2, (b) Pt3/Co/Pt3, (c) Pt2/Co/Pt4, (d) Pt2/Co/Pt4 with constant sample temperature, and (e) Pt4/Co68B32/Pt2 with constant sample temperature. The blue and red filled symbols/solid line (open symbols/dashed line) correspond to the current flowing with (against) the direction of DWM, to the right, as indicated by the arrows in Fig. 1(d). Note that the top-axis scale is non-linear.

FIG. 3.

Average DW velocity as a function of current density |J| for constant |μ0 H z| = 21 mT for both polarities of the Pt4/Co/Pt2 sample.
