Extended Data Fig. 4: Additional skyrmion velocity measurements via the nonlinear topological Hall effect – device 3 and 4.
From: Dynamic transition and Galilean relativity of current-driven skyrmions
a, The Hall resistivity ρyx measured at 2.5 K as a function of the applied magnetic field \(B\) at three current densities JDC for device 3. b, The change in the Hall resistivity Δρyx(J) = ρyx(J) − ρyx(J→0), normalized by the zero current limit value of the Hall resistivity, ρyx(J→0), measured as a function of JDC, at 2.5 K and various applied fields in device 3. c, The skyrmion velocity, vSk, plotted as a function of J, calculated from the data in b, for various applied fields in device 3. d-f, The same as a-c, but for device 4.
