Figure 4
The Fourier transform (FT) of k3χ(k) for (a) YbAgCu4 and (b) YbCdCu4. The outer envelope represents ± the amplitude and the oscillatory line within the envelope is the real part of the complex transform. These transforms are from 2.5 to 15 Å−1 and are Gaussian narrowed by 0.3 Å−1. Fits are from 2.0 to 3.2 Å. |
