Abstract

Using the double high-speed photography method, the dynamics of domain walls in a ferrite–garnet film is studied under an in-plane magnetic field close in magnitude to the anisotropy field. To explain the obtained nonlinear relation between the domain wall mobility and dc magnetic field oriented in the film plane perpendicular to the domain wall plane, we use the assumption about the dependence of the damping parameter on the in-plane field, which becomes appreciable under the in-plane field exceeding 40% of the sample anisotropy field.
