Fermi surface nesting in disordered Cu1-xPdx alloys.
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.
