Abstract

It has been shown that the strength of the perpendicular magnetic anisotropy (PMA) in Palladium/Cobalt (Pd/Co) bilayer films can be altered by exposing them to hydrogen. This change in PMA strength can be measured with ferromagnetic resonance spectroscopy. Based on this technique, the magnetic hydrogen gas sensor (mHGS) was proposed in 2014. In this work, various materials based on Co and Pd were investigated as sensing media for the mHGS. In five mutually connected projects, the effect of hydrogen on the magneto-dynamics of Co/Pd multilayer films and nano structures, NiCoPd alloy thin films and microresonator structures loaded with CoPd alloys were investigated.
