Spin wave propagation in anisotropic monocrystalline iron stripes — •Helmut Körner, Johannes Stigloher, Matthias Kronseder, and Christian Back — Institut für Experimentelle und Angewandte Physik, Universität Regensburg, Germany

Pure iron might be a suitable candidate for spin wave based applications due to its promising properties such as low damping factor, high saturation magnetization and well-defined magneto-crystalline anisotropy, calling for profound investigations of spin wave propagation in this material. Our sample is a Fe(10 nm)/AlOx(5 nm) full film grown on top of a GaAs substrate by means of molecular beam epitaxy showing a pre-dominant cubic magneto-crystalline anisotropy which is then patterned into micrometer-sized stripes with different orientations with respect to the crystallographic axes of the iron. In these stripes, we study the propagation of electrically excited magneto-static Damon-Eshbach spin waves employing time-resolved scanning Kerr microscopy in combination with micromagnetic simulations using the GPU-accelerated simulation program mumax3.
