Extended Data Fig. 7: Calculated energy barriers and prefactors for skyrmion creation.
From: Experimental identification of two distinct skyrmion collapse mechanisms
a-c, Energy barriers (black) and prefactors (blue) for the radial symmetric (open symbols) and chimera type creation (full symbols) of an isolated skyrmion at varying B∥ according to atomistic spin simulations via GNEB and transition state theory based on parameters from DFT (methods). (a) B⊥ = 3.2 T, (b) B⊥ = 4.0 T, (c) B⊥ = 4.3 T. d, Thermal creation rates at B⊥ = 4.3 T resulting from (c) using eq. (1) for three different temperatures with filled (open) circles employing the chimera (radial symmetric) creation process. Trends are similar as for the collapse mechanisms (Fig. 5), but the creation rates (d) depend much less on B∥ than the collapse rates (detailed discussion in Supplementary Section S11).
