Fig. 5: Velocities of chiral bobber (ChB)/skyrmion tube (SkT) and the threshold of the driving field for the ChB motion.
From: Spin-wave-driven tornado-like dynamics of three-dimensional topological magnetic textures
a The velocities of the SkT and ChBs with different penetration lengths LB as functions of the driving field hrf. The solid curve corresponds to a fitting of the SkT velocity with a quadratic function. b Threshold of the driving field \({h}_{{{{{{{{\rm{rf}}}}}}}}}^{{{{{{{{\rm{c}}}}}}}}}\) for the ChB motion as a function of penetration length. The blue solid line is a linear fit of the ChB data and the dashed line shows the extrapolation to the length of the SkT. The error bars in b represent half of the step size (0.025 T) of the magnetic field during the calculation.
