abstract = {Local atomic order in series of Al–(Y, Sm)–TM (TM =
transition metal: Co, Ni) amorphous, melt-spun alloys was
investigated by Sm$L_3$-edge and TM$K$-edge X-ray absorption
fine structure (XAFS) method. The evaluated coordination
number of Sm is approximately 16 for all investigated
systems and TM coordination ranges form 5 to 6. A slight
decrease in TM coordination along with increase of TM
content is observed. The interatomic distances between Al
and Sm atoms are equal to the sum of their metallic radii
within the experimental error, while Al–TM bonds are
shortened by 10\%10\%. The structural disorder around Sm
atoms is significantly higher then around TM. We have found
that only Al atoms are present in the first coordination
shell of both Sm and TM species. The XAFS data show that the
amorphous network coherency is lost at distances exceeding 4
Å. The results are discussed in a framework of Miracle’s
structural model of metallic glasses suggesting that the
average local structure around Sm atoms consists of 16
efficiently packed Al atoms in the first coordination shell
of Sm and the TM atoms occupy the octahedral sites in the
closely packed fcc cluster structure.},
