The formation and the dynamics of the domain walls in magnetic nanowires have been studied by micromagnetic simulations.

Simple criteria for making distinction between Stoner-Wohlfarth type and nucleation mechanisms in nanowires were discussed.

Corkscrew domain walls or quasi-coherent spin rotation may be induced depending on the field orientation.

The nucleation time was estimated at 3 ns and the wall velocity at 150 m/s.

A simple way for tuning the wall velocity in such systems was mentioned.
