Abstract

We investigate the magnon dispersion of spinwaves propagating in a Permalloy stripe and compare it to a plain film. We use a Scanning Kerr Microscope to directly image their spatial propagation- and decay properties as well as micromagnetic simulations to extract additional information about the static magnetization distribution. For low external fields, we find anti-crossings for the dispersion branches corresponding to different transverse wave vectors that also occur as minima of the decay length for the spinwave.
