Previously, it has been shown that the strength of the perpendicular magnetic anisotropy (PMA) of thin palladium (Pd)-cobalt (Co) bilayer films can be modified when hydrogen gas is absorbed by the Pd layer. In our recent work, we showed that the ferromagnetic resonance (FMR) response of this material is sensitive to the changes in PMA upon exposure of Pd to hydrogen gas. As such, a simple, compact, and contactless hydrogen gas sensor could exploit the FMR-based detection of the reversible… Expand
