From: Impact of higher-order exchange on the lifetime of skyrmions and antiskyrmions
a Energy barriers (black) and pre-exponential factors ν0 (purple) of skyrmions (filled circles) and antiskyrmions (open circles) in fcc-Pd/Fe/Ir(111) considering HOI and vanishing DMI for varying the magnetic field relative to the critical field B⊥ − BC. b Radius of skyrmions and antiskyrmions as a function of the magnetic field. c Mean lifetime τ (see colorbar) of the above mentioned isolated magnetic textures as a function of the temperature T and the external magnetic field B⊥ − BC.
