Fig. 2: Current-induced magnetization switching and chiral ___domain wall displacement.

a Current-induced magnetization switching measured under \({H}_{{\rm{x}}}=\pm 100\ {\rm{Oe}}\). The switching polarity is marked by the colored arrows. b Reversible magnetization switching induced by two opposite pulsed current of \(\pm 9\,{\rm{mA}}\) at \({H}_{{\rm{x}}}\,=\,+100\,{\rm{Oe}}\). c The schematic illustration of the left-handed chiral Néel DWs without the application of in-plane magnetic field, where the effective field \({H}_{{\rm{SL}}}\) associated with a Slonczewski-like torque drives adjacent up-to-down and down-to-up DWs moving towards the same direction with respect to the current. d The corresponding situation when a magnetic field is applied along \(+\hat{{\bf{x}}}\) direction, where the left-handed up-to-down DWs changes into the right-handed up-to-down DWs, resulting a reversion of both the \({H}_{{\rm{SL}}}\) and the DWs motion direction. e Up-to-down (abbreviated as UP-DN, red circles) and down-to-up (abbreviated as DN-UP, blue squares) ___domain wall velocity as a function of out-of-plane magnetic field \({H}_{{\rm{z}}}\) under \({I}_{{\rm{CH}}}\,=\,+2\,{\rm{mA}}\). f Domain wall velocity versus in-plane magnetic field \({H}_{{\rm{x}}}\). Red and blue symbols represent up-to-down and down-to-up DWs, respectively. Square and circular symbols correspond to positive and negative currents, respectively.
