The local structure of Nd-Fe-B amorphous alloys was studied by Nd L(3)
XAFS. The amorphous alloys were prepared by melt-spinning, mechanical
grinding and mechanical alloying techniques. It was concluded that th
e local structures around the Nd atoms of the amorphous alloys strongl
y depend on the difference of fabrication technique, especially the am
orphous alloy produced by mechanical alloying which has a quite unique
local structure.
