Abstract

The local structural properties of nanoparticle CeAl₂ were studied by X-ray absorption fine structure measurements at the Ce L ₃-edge. These studies show that the nanocrystalline material is severely disordered compared to its bulk counterpart and that the bond length of Ce-Al in the nanoparticle is about 0.4 A shorter than that in the bulk. These observations strongly suggest that in addition to size and surface effects, structural disorder plays a role in determining the Kondo behavior in this nanocrystal.
