Levitating antenna on glass for spin wave exitation and detection

Prototyp

This document describes the fabrication of reusable and positionable microwave antenna on glass suitable for spin-wave excitation and detection. Nowadays spectroscopic techniques for the investigation of magnetization dynamics in micro and nanostructures typically use microwave antennas directly fabricated on top of the sample by electron-beam lithography (EBL). However, this approach requires often multistep EBL processes and special antenna for each structure. In contrary our approach is reusable, and antenna can be landed on multiple structures on multiple samples. Since we use flexible transparent glass as the antenna substrate, optical spectroscopy techniques like microfocused Brillouin-light-scattering microscopy (μBLS), time-resolved magneto-optical Kerr-effect measurements, or optically detected magnetic resonance measurements can be carried out at visible laser wavelengths.
