Preferential sputtering of Cu-Ni alloys has been investigated using the Ion Scattering Spectroscopy (ISS). We have observed the preferential sputtering of Ni in low Ni alloys and of Cu in low Cu alloys when sputtering them with 0.8 and 3.0 keV Ne+ beams. Current models which consider mass and surface binding energy predict the behavior for Cu but not for Ni.
