Spin-Wave Reciprocity in the Presence of Néel Walls — •Lukas Körber, Kai Wagner, Attila Kákay, and Helmut Schultheiss — Helmholtz-Zentrum Dresden - Rossendorf, Bautzner Landstraße 400, 01328 Dresden, Germany

We report on the reciprocity of channeled spin waves in a 180° Néel wall with special focus on the in-plane curling of the magnetization. In particular, the dispersion relation, phase fronts and frequency-dependent spin-wave intensites where studied by means of micromagnetic simulations. Despite the strong curling of the magnetization at the center of the Néel wall, non-reciprocity is only found in the domains whereas the wall acts as a reciprocal channel.
