Design and construction of a spin-wave lens

In this work, we present the focusing of a Damon-Eshbach wave in a Ni(80)Fe(20) film by a shaped, discrete transition of the film thickness. We devised an algorithm to determine the required shape of a spin-wave lens. Due to the anisotropy three geometries qualify as plano-convex lenses. One lens ge...

description In this work, we present the focusing of a Damon-Eshbach wave in a Ni(80)Fe(20) film by a shaped, discrete transition of the film thickness. We devised an algorithm to determine the required shape of a spin-wave lens. Due to the anisotropy three geometries qualify as plano-convex lenses. One lens geometry has been realized experimentally and the emitted spin-wave pattern is investigated by time-resolved scanning Kerr microscopy.
