a-d, Representative time traces recorded during ten individual SOT-dominated P-AP switching events induced by 15 ns long pulses with a,b, VSOT= +453 mV, VSTT= −227 mV and c,d, VSOT= +481 mV, VSTT= −242 mV at a,c, μ0Hx= −23 mT and b,d, μ0Hx= −90 mT. The time traces have been offset for clarity. Black solid lines are fits with a linear ramp used for extracting t0 and Δt. e-h, Distributions of e, t0 and f, Δt at μ0Hx= −23 mT, and g, t0 and h, Δt at μ0Hx= −90 mT. The histograms are obtained from the analysis of 1000 single-shot switching events.
