Ferromagnetic resonance and travelling spin-wave spectroscopy of thin magnetic films of interest for applications

Dynamic magnetization phenomena such as ferromagnetic resonance and propagating spin waves have been of significant research interest for potential applications in areas such as sensing, computation, and memory storage. In this PhD project, we theoretically and experimentally explored spin waves via microscopic stripline antennas deposited on ferromagnetic based Ru/Co/Pt trilayer thin films, on the nanometre thickness scale. Additionally, we utilized Ferromagnetic Resonance spectroscopy to detect the presence of hydrogen gas in thin Py/Y/Pd trilayer films. Both of these projects have potential for applications, such as magnetic spin wave logic devices and magnetic hydrogen gas sensors.
