Cu_（1-x）Pd_x合金在无序状态下的电子和X射线衍射图中扩散峰的浓度依赖性位置归因于费米面嵌套。我们提出了第一个实验确定的费米表面的Cu0.72Pd0.28和Cu0.6Pd0.4，并表明，他们确实具有显着的平坦区域能够嵌套。此外，嵌套矢量的大小与电子结构计算和衍射实验推导出的结果非常一致。
The concentration-dependent position of the diffuse peaks in electron and x-ray diffraction patterns of Cu1-xPdx alloys in the disordered state is attributed to Fermi surface nesting. We present the first experimentally determined Fermi surfaces of Cu0.72Pd0.28 and Cu0.6Pd0.4, and show that they do indeed possess significant flat areas capable of nesting. Moreover, the magnitudes of the nesting vectors are in excellent agreement with those deduced from electronic structure calculations and diffraction experiments.
