| Abstract: | The local structure in hydrogenated amorphous LaNi5.0 film was analysed by means of extended X-ray absorption fine structure. The short-range order in the amorphous LaNi5.0 film was found to be little affected by the absorption of hydrogen. The lengthening of the interatomic distance with an increase in hydrogen concentration was much smaller for an amorphous film than for a crystalline bulk, so that the amorphous film appears to have excellent durability with regard to the hydrogen absorption-desorption process. |
