Figure 6
The bond-length distribution variance for the U–Cu pairs at ∼2.93 Å as a function of x in UPdxCu5−x. The `cold' results are for the lowest temperature collected for that value of x, between 4 and 20 K. was determined by fits of the temperature-dependent data to the correlated-Debye model, as described in the text. The hatched area shows the approximate amount of disorder necessary for lattice disorder to explain fully NFL behavior in the x = 1.0 and 1.5 compounds based on the Kondo disorder model. |
