Abstract
The effect of motion on two-dimensional solitons (skyrmions) in the Heisenberg ferromagnet is considered. First, it is shown that these excitations become vortexlike with a small in-plane spin component far from the excitation center and the original circular symmetry of the excitation is broken by motion. Second, the out-of-plane dynamic correlation function is calculated and it is shown to have a modified Gaussian central peak.Keywords
