We investigate magnetic properties of Fe thin films on Cu(111), within the density functional theory. We calculate the total energy and the magnetic moment as a function of the Fe–Cu interlayer distance d. We find the energy minimum at d=2.16 Å. In this case, the magnetic moment per atom is larger than that in the Fe bulk. We also find that interaction between Fe atoms is ferromagnetic in 2× 2 unit cell. On the basis of numerical results, we discuss the origin of these magnetic properties.
