Abstract
It is shown, using the example of epitaxial ferrite—garnet films with (111) orientation whose dimensionless damping parameter was varied over a wide range, that for uniaxial magnetic films the mechanism of the motion of the domain walls is universal and includes local rotation of the magnetization ahead of the moving domain wall. The threshold field for the transition to this mechanism of motion of the domain walls is proportional to the uniaxial magnetic anisotropy field. On the curve of the dependence of the domain wall velocity on the acting magnetic field, this mechanism corresponds to the section with increased differential mobility of the domain walls.
