    Abstract

    A new concept of magnetic hydrogen gas sensing (m-HGS) is explored in this thesis. A wide detection range (0.1 to 100
    percent) of hydrogen gas (H2) is achieved based on the effect of a decrease in strength of the perpendicular magnetic
    anisotropy at the interface of Palladium (Pd) and Cobalt (Co) layers upon Pd exposure to H2 .The physics underlying this
    concept is discussed. The focus is on the ferromagnetic resonance response of Pd-Co materials in the presence of H2. Several
    types of films (Bi-layer Pd/Co, trilayer Pd/Co/Pd and CoPd alloy) are designed and investigated as H2 sensing media.
