Structural Studies on Amorphous LaNi_5.0 Films as Prepared in Different Methods

Abstract

Investigation of the local structure around La and Ni atoms in the amorphous LaNi5.0 films prepared by the evaporation and sputtering methods was carried out by means of EXAFS. The short range order in the evaporated film resembled that in the sputtered one and the hydrogen concentration dependence on the change in the local structure in these films well coincided, so that the hydrogen in these films appears to be occupied in the same hydrogen sites.

EXAFS Debye–Waller factors of La and Ni in LaNi5

“…The studies of EXAFS for LaNi 5 and its hydride are quite limited so far, especially on the temperature dependence of the DW factors of La and Ni [7][8][9][10]. In the present work we measured the EXAFS of the Ni K-edge and the La L 3 - …”
