Abstract
Within the framework of the continuum theory of micromagnetism the interaction of spin waves with domain walls is studied. By numerical simulations based on the finite element method a ferromagnetic Co stripe is modelled. The ground state is a homogeneous magnetization state on both sides of the stripe separated by a 180° Néel-type domain wall. On one side of the stripe monochromatic spin waves with well-defined frequency and propagation orientation are excited. At the domain wall the spin wave is reflected and/or transmitted. The corresponding fractions are analyzed. For wavelengths larger than the wall width we observe a full reflection of the spin waves while for smaller wavelengths the spin waves transmit by 100%. Depending on the frequency the phase of the spin waves can shift within a wide range.
