a The normalized out-of-plane Hall curves measured under a fixed in-plane magnetic field of Hx = +600 Oe and opposite d.c. currents of \(\pm 4\,{\rm{mA}}\). b The \({H}_{{\rm{shift}}}^{{\rm{z}}}\) as a function of \({I}_{{\rm{DC}}}\) under different bias fields. The solid lines are linear fittings to the data. c, d The switching fields \({H}_{{\rm{SW}}}\) for down-to-up (DN-UP, red squares) and up-to-down (UP-DN, blue circles) magnetization reversals as a function of \({I}_{{\rm{DC}}}\) with Hx = +600 Oe and Hx = −600 Oe, respectively.
