a,b, Representative time traces recorded during ten individual SOT-induced AP-P switching events induced by 15 ns long pulses with VSOT= +453 mV and increasing STT bias VSTT= −227, +266, +513 mV at a, μ0Hx= +23 mT and b, μ0Hx= +90 mT. c,d, Representative time traces recorded during ten individual STT-induced AP-P switching events at VSTT= +884 mV and c, μ0Hx= +23 mT and d, μ0Hx= 0 mT. The pulse amplitudes are the minimum ones required to achieve 100% switching in any of the shown configurations. The time traces have been vertically offset for clarity. Black solid lines are fits with a linear ramp used for extracting t0 and Δt. e, Statistical distributions of the incubation time t0, f, the transition time Δt and g, the total switching time t0+Δt at μ0Hx= +23 mT for SOT switching at different STT biases . h, Statistical distributions of t0, i, Δt and j, t0+Δt at μ0Hx= +90 mT. The histograms are obtained from the analysis of 1000 single-shot switching events.
