Sensing hydrogen in the gas phase using ferromagnetic Pd–Co films

Self-Consistent Diffraction Stress Analysis Method for Estimating Stress, Strain-Free Lattice Parameter and Composition of Solid Solutions

“…In the magnified view, peak positions of 111 and 11 1 are distinguishable with a slight difference seen in as deposited films, suggesting small residual stress in the films (details are discussed later). In contrast, a large difference is observed on annealed films, and because the 111 peaks at a higher angle compared to 11 1, the (111) lattice spacing is smaller than the ð11 1Þ spacing. This indicates the existence of large in-plane tensile stress in the films.…”

Hydrogenation Effect on Interlayer Coupling and Magneto-Transport Properties of Pd/Co/Mg/Fe Multilayers

“…Pd is a popular hydrogen storage material because of the highly catalytic H 2 dissociation of the Pd–H system at room temperature (RT) . Because of the high hydrogen sensitivity , and high magnetic susceptibility of a Pd system, Pd hydride can effectively induce electron exchange in magnetic materials and indirectly affect their magnetism. − However, a Pd system is not sufficiently stable to preserve the hydrogen in the crystal lattice at RT and is only suitable for hydrogen sensor development. Additionally, the high cost and low production of Pd make it unfavorable for industrial applications.…”

Modulation of Spin Seebeck Effect by Hydrogenation

“…Magnetic multilayers and super-lattices which include Pd layers have been of particular interest. It was reported that in Co/Pd bilayers which possess a strong interfacial perpendicular magnetic anisotropy, the magnetic anisotropy and ferromagnetic resonance are reversibly modulated by hydrogen exposure [5][6][7][8][9][10][11] . Efficient hydrogen sensing based on magnetization dynamics was also reported in similar materials 5,12,13 .…”
