The magnetic properties and growth mode of self-assembly alloy nonoclusters
were interests to surface science. Our experiment focused on the growth behavior
of Fe-Ag alloy nanoclusters on the ordered alumina templates. We carried out
the experiment by scanning tuneling miscoscopy (STM) under an ultra high vacuum
chamber with base pressure better than 5 x 10E-11 torr. The clean NiAl(001)
surface was prepared by repeating argon sputtr and annealing. Subsequently, it
was deposited 1000 L oxygen at elevated temperature to form the ordered alumina
templates. Iron and silver nanoclusters were deposited simultaneously on
Al2O3/NiAl(001) surface by electron-beam evaporators. We observed the alloy
nanoclusters by STM at low temperature. By increasing the silver composition,
the height and diameter of alloy nanoclusters was increase, but the increasing
ratio of diameter is higher than that of height.
