Fig. 4

a Anomalous Hall effect in the Pt showing clear hysteresis from the magnetization of the adjacent LAFO layer. Inset: optical image of the Hall bar with measurement geometry. The Hall bar dimensions are 10 μm × 40 μm. b Rxy measured as a function of JDC at Hx of ± 3 mT along the current direction. c Rxy measured with a sequence of current pulses of alternating sign for Hx of ± 3 mT along the current direction. d Critical switching current density Jc as a function of in-plane field. The inset shows the switching loops for μ0Hx = 2.0 mT and μ0Hx = 8.5 mT. The uncertainty is obtained from the width of the transition.
