Abstract

Amorphous Fe90Zr10 and Fe91Hf9 ribbons were charged with hydrogen by the electrochemical method up to Fe90Zr10H26 and Fe91Hf9H15, respectively, and the change in magnetic structures were analyzed by Mössbauer spectrometry. The internal magnetic field appeared by the charge of hydrogen, the degree of change being depended on amounts of hydrogen included in amorphous Fe90Zr10 and Fe91Hf9, although Fe91Hf9 absorbed hydrogen more slowly than Fe90Zr10. The differences of hydrogen inclusion and Mössbauer hyperfine structure between Fe90Zr10 and Fe91Hf9 were discussed based on the results of a hyperfine field distribution and the radial distribution functions of Fe-Fe obtained by EXAFS.
