Abstract Micromagnetic simulation of a current-driven vortex domain wall motion in a film with in-plane anisotropy was carried out. The current density values j > j c were considered corresponding to the nonstationary motion, with the domain wall structure dynamic transformation occurred. A nonlinear dependence of the j c value on the film thickness was obtained. The nonstationary motion regime existence restricted the possibility to increase the domain wall velocity by increasing j and decreasing the damping parameter.
