Magnetostatic surface waves on a steadily moving domain wall

Magnetostatic surface waves on a steadily moving domain boundary of a ferro garnet crystal are considered in the exchangeless magnetostatic approximati on. It is shown that the structure and spectrum of a magnetostatic surface wave can be significantly modified under the effect of motion of the bounda ry concentrating the field. It is also found that the parametric transforma tion of the magnetostatic surface wave due to the motion of the domain boun dary is greater when the angle between the magnetization axis and the wave vector decreases.
