(a), (b) Contour plots of dV/dI as a function of both the dc bias and the applied magnetic field, with the field-sweep directions from the AP to P state and from the P to AP state, respectively. (c) Schematic of the switching
boundaries, with the area of interest divided into several typical regimes.
