Abstract

We report the results of complex studies concerning skyrmion motion in U-shaped and V-shaped nano-tracks simulated with MuMax3. The Thiele equation was used for description of skyrmion velocity components. It was shown that both size and velocity of a skyrmion vary depending on its position in the system, featuring distinct values for the straight and curved branches of the track. The degree of velocity variation can be effectively controlled by geometry of the track (including track width and its curvature radius) as well as the density of the driving current applied to the system.
