English Mg–Al thin films with a compositional gradient are co-sputtered from off-centered magnetron sources and capped with a thin Pd layer. We study their hydride formation by monitoring their optical transmission during hydrogenation under defined pressure and temperature conditions. We find that Mg(AlH₄)₂ is already formed from the elements at p(H₂)=1 bar and T=100 ° C. A thin layer of Ti acts as a catalyst. Doping of Mg–Al with Ti has a negative influence on hydrogen absorption.
