Extended Data Fig. 2 | DW inversion in a DW inverter with a straight IP
region. a, STXM image sequence of DW inversion for an incident ⊗|⊙ DW
performed in a DW inverter with a straight IP region. Each XMCD image is
captured after the application of two current pulses. The edges of the magnetic
racetracks are indicated with red dashed lines and the positions of the inverters
are indicated with solid white lines. The bright and dark regions in the XMCD
images correspond to ⊙ and ⊗ magnetization, respectively. The current
density and duration of the pulses are 1.1 × 10^12 A m−2 and 1 ns, correspondingly.
b, STXM images of the nucleation of reversed magnetic domains in the same
DW inverter for four different operations. c, DW velocity in inverters with
V-shaped and straight IP regions as a function of current density, determined
from the experimental MOKE measurements. Error bars and shading represent
the standard deviation of the DW velocity for 5 measurements. All the scale bars
are 500 nm.
