Within local-spin density approximation, the electronic and magnetic structures of the finite-size systems of Fe/Au(n) (n = 2-12) are studied. These systems consist of n layers of Au possessing the interface with Fe monolayer on one side and the free surface on the other. The magnetic moment at the surface Au layer rapidly decreases with the increasing number of Au layers. The decreasing behavior of the surface Au layer is quite different from that in the inner Au layers. With increasing number of Au layers, the magnetic moment of Fe monolayer shows non-monotonic change with size of 0.1 μB.
