Streszczenie:
The calculations of the inelastic spin wave scattering by flexure vibrations of the Bloch domain wall (Winter’s magnons) in thin magnetic films are presented. The approach is based on the interaction of the propagating spin waves with the dynamical emergent electromagnetic field generated by the moving inhomogeneous magnetization texture (domain wall). The probability of the spin wave scattering for the Winter’s magnon emission and absorption processes essentially rises with the spin wave scattering angle increase up to 90. The angular dependence of the scattering probability is essentially stronger for the magnon absorption processes that allow distinguishing these elementary emission/absorption processes experimentally.
