This synthesis technique allows continuous variation in stoichiometry, while the distribution of Ag or Pd atoms retains the arrangement into an on-average periodic lattice with smoothly varying unit cell parameters. The alloy concentration and geometry were measured over a set of sample points, respectively, via energy-dispersive X-ray spectroscopy and via X-ray diffraction. These results are compared with ab initio total energy and electronic structure calculations based on DFT, and using the CPA for an effective medium description of disorder. Lattice parameters appear in qualitative agreement with the measured trends. The numerical study of the Fermi surface also shows a variation in its topological features, which follow the change in Ag concentration. These were related to the electrical resistivity of the alloy.
