Micro-stripline mediated emission and detection of spin wave propagation in permalloy thin films — •Klaus Thurner, Georg Dürr, Sebastian Neusser, and Dirk Grundler — Lehrstuhl für Physik funktionaler Schichtsysteme, Technische Universität München, Physik Department, James-Franck-Straße 1, D-85747 Garching b. München, Germany

We report spin-wave propagation experiments performed on ferromagnetic Ni80Fe20 (permalloy) thin films in the frequency domain. Spin waves are induced and detected by a pair of collinear coplanar waveguides (CPWs) connected to a broadband vector network analyzer. Tailored designs of both emitter and receiver CPWs for efficient and predefined spin-wave excitation are investigated. Electromagnetic impedance matching and wave vector matching to the spin-wave dispersion relation of permalloy are taken into account. The measurements are performed at room temperature with an in plane magnetic field applied in different directions. We acknowledge financial support through the German excellence cluster “Nanosystems Initiative Munich”.
