Abstract
The influence of nuclear energy deposition density (epsilon) on the io n-beam mixing process is studied in the case of Ni-Zr and Fe-Zr bilaye rs. Nickel and iron crystals covered with a thin zirconium layer were irradiated at liquid nitrogen temperature with ions of various masses (from N to Xe), which provide values of epsilon in the range 25-440 eV /Angstrom. The mixing parameters were determined via in situ RES durin g irradiation. The variance of the distribution function of mixed atom s (sigma(2)) is found to increase linearly with the ion fluence for al l the ions used in the experiment. The mixing rate exhibits a linear v ariation with epsilon, above a threshold of similar to 25 eV/Angstrom, for the two systems studied.
