Abstract

MmNi_3.5(CoAlMn)_1.5/Mg (here Mm denoted for mischmetal) multi-layer thin films were deposited on (001) Si substrate by direct current (dc) magnetron sputtering with dual-target. X-ray diffraction (XRD) and scanning electron microscopy analysis revealed that the microstructure of the MmNi_3.5(CoAlMn)_1.5 layer is amorphous and/or nanocrystalline and that the microstructure of the Mg layer is fine grained crystalline with preferential orientation. Phase analysis of hydrogenated and dehydrogenated MmNi_3.5(CoAlMn)_1.5/Mg multi-layer thin films proved that an apparent absorption of hydrogen in the Mg layer occurs at temperatures higher than 200°C and that the hydrogen absorbed can be fully released at 250°C. © 2003 Elsevier B.V.
