Extended Data Fig. 8: Comparison of calculated and experimental skyrmion creation rates.
From: Experimental identification of two distinct skyrmion collapse mechanisms
Thermally induced skyrmion creation rates at different T deduced with the help of eq. (1) using the theoretical parameters from atomistic spin simulations of Extended data Fig. 7a (colored lines, B⊥ = 3.2 T) and experimental skyrmion creation probabilities per single electron (Fig. 6g) extrapolated to creation rates for an assumed I = e/2 fs = 75 μA (symbols, B⊥ = 1.5 T). This large I would establish a quasi-constant temperature of 45 K within the hot spot area of increased energy density at the SP according to our finite element simulation as displayed in Fig. 6h (detailed discussion in Supplementary Section S11). Experimental data of two skyrmions are displayed exhibiting barely any difference. Error bars result from the uncertainty of the adaption of I to a continuous T.
