Magnetostatic surface waves in a moving domain wall of a ferromagnetic crystal with regard to the external magnetic field

Abstract Magnetostatic surface waves in a uniformly moving domain wall are considered taking into account the difference between the frequencies of ferromagnetic resonance in the domains, which is caused by the external magnetic field. It is shown that the magnetostatic wave is able to modify significantly the form of the spectrum under the influence of motion of the guiding wall, which is caused by the external field, without changes in the structure of the wave. Two types of behavior of the spectral branches in the dependence of the frequency of the magnetostatic wave on the external field upon a change in the range of wave numbers of the wave are found.
