Abstract
One-dimensional transition metal (TM) nanowires can be formed on a stepped Cu(111) surface. The basic template is an embedded Fe chain at one-atom distance away from the upper edge of the monoatomic surface step, supplying the deposition of 3d TM chains from V to Co to form on top of the Fe chain. Density functional theory (DFT) is applied to calculate the magnetic properties of these TM-Fe wires. Exchange parameters are extracted from the DFT calculations. A classical Heisenberg model is used in Monte Carlo simulations to study finite temperature effects.
